I decided to introduce my son to video games. We soon found one he liked … and I mean really, really liked

So I decided to introduce my two-year-old son to the world of video games. Before you accuse me of hobbling my offspring's mind, I'd like to point out that a) television is 2,000 times worse, so shove that up your Night Garden and b) I also decided to counterbalance the gaming with exposure to high culture. For every 10 minutes of Fruit Ninja during daylight hours, he'd get 10 pages of a critically acclaimed novel at bedtime. We're currently halfway through The Magus by John Fowles, which he's enjoying immensely. He finds some passages so moving that his protracted sobs drown out my reading completely, and when I return to the beginning of the chapter to start again, he leaps up screaming, trying to snatch the book out of my hands with delight.

Like any self-respecting 2014 toddler, he can swipe, pat and jab at games on a smartphone or tablet, but smartphone games aren't real games. They're interactive dumbshows designed to sedate suicidal commuters. And they're not just basic but insulting, often introducing themselves as free-to-play simply so they can extort money from you later in exchange for more levels or less terrible gameplay. Either that or they fund themselves with pop-up adverts that defile the screen like streaks on a toilet bowl.

LOCKDOWN measures could turn the UK into "postcode lottery" as police forces admit they will not pursue low level speeding offences amid the restrictions.

MARTIN LEWIS has urged motorists to maintain their car in a good condition to prevent drivers from "shelling out" for repairs once the coronavirus lockdown is lifted.

LOCKDOWN measures have broken motorists' "car dependency" habits and the changes could even be "permanent" for many after restrictions have lifted, according to an expert.

The president of Texas Motor Speedway is still hoping to run the Genesys 600 with fans in June. But if they're turned away, he'll need NASCAR's help.

IndyCar will host its season-opener at Texas Motor Speedway on June 6 as planned, but without fans and in a one-day show.

Ordinary people in their ordinary cars take to the drag strip to get their need for speed.

• I tested a roughly $33,000 Polaris Slingshot R, a three-wheeled "autocycle."
• The three-wheeler category includes vehicles from Can-Am and Harley-Davidson, offering a motorcycle experience in a less demanding package.
• My Slingshot R had a new, Polaris-developed, 203-horsepower engine and an automatic transmission.
• In all but three US states, no motorcycle license is required to operate the Slingshot (New York, Massachusetts, and Alaska continue to require the motorcycle certification).
• The Slingshot is insanely fun, with a modest learning curve — it's a great alternative to a two-wheeler, although the price is definitely steep for the Slingshot R.

Motorcycles are cool, but they aren't for everybody. Fortunately, there are some alternatives out there that offer an equally compelling, open-air experience.

One of the most popular is the the Polaris Slingshot, manufactured by the Minnesota-based powersports company. Until recently, Slingshots were available only with manual transmissions and GM-sourced engines, but for 2020, Polaris has updated the autocycle with an in-house motor and an automatic.

The automatic transmission in particular really broadens the Slingshot's potential. So I was excited to sample the machine, which I first saw about five years ago.

Polaris was kind enough to loan me a tester for a few weeks. Here's how it went:

The Polaris Slingshot is a three-wheeled autocycle/motorcycle that Polaris industries has produced since 2014. My 2020 Slingshot R tester cost about $33,000 and was outfitted in a menacing red-and-black paint job.

The cheapest Slingshot is about $20,000.

This wasn't my first crack at a Slingshot. Polaris brought the vehicle to Insider's New York offices when the vehicle first launched.

And I generally have a gander at the Slingshot when I visit the annual New York motorcycle show.

The Slingshot is classified as either a motorcycle or an autocycle, depending on which state it's being operated in.

Yep, it looks like the Batmobile. Or Batcycle. Hard to avoid feeling like a superhero when you're behind the wheel. In all but three US states, no motorcycle license is required to drive the Slingshot. In New Jersey, you are required to wear a helmet.

Up front, you have 18-inch forged aluminum wheels, with an 20-incher at the back. The brakes have two-piece composite rotors.

Permanent open-air motoring isn't for everybody. Polaris does sell and older model, the Grand Touring, which has a cockpit canopy. The Polaris R has a waterproof interior and drain holes in the floorboards, should you get caught in bad weather.

My tester was the top-level "R" trim, complete with dual roll bars for drier and passenger.

Let's talk fender fairings! The Slingshot's are dramatic and large — I was reminded of Chevy Corvettes while driving this thing. Like a motorcycle, there's no rear-view mirror, so you have to adjust slightly to using the sideviews.

There's a new engine under the hood. Previously, Polaris used a 2.4-liter, four-cylinder GM-sourced Ecotech motor, making up to 175 horsepower. But my R had a ProStar four, also at 2.4-liters, cranking out 203 horsepower with a five-speed automatic transmission (a manual remains available). It's an in-house engine that was impressive in action.

The top speed is limited at 125 mph, and the 0-60mph run, according to Polaris and confirmed by yours truly, is about five seconds.

The four-banger redlines at 8,500 rpm and even with the automatic transmission does a pretty fair imitation of proper motorcycle acceleration. The auto is a tad crunchy, but in this context, that's a plus. It keeps you aware of what the engine is doing.

The rear wheel — fat and wide — is yoked to the motor and transmission with a belt drive. The suspension is surprisingly compliant, but you do have to be mindful of bumps, potholes, and manhole covers if you want to preserve you lower spine.

Polaris says the interior has been upgraded for 2020. No one would call it premium, but for a vehicle like this, it's rather comfortable.

The steering wheel is leather-wrapped, multifunctioned, and flat-bottomed to make getting into and out of the driver's seat easier.

The instrument cluster is a basic analog affair with a central digital display. The red button to on the right steering-wheel spoke allows you to switch between Comfort and Slingshot modes (the latter being the high-performance option).

The bucket seats are waterproof and extremely well-bolstered, with three-point seat belts.

The Slingshot's tubular frame is apparent in the doorless frame.

Not really much cargo capacity here, although I did use the Slingshot for a grocery-store run and quick jaunt to Target to buy a basketball.

There is a place to stow a smartphone, located just above the push-button gear selector.

The Slingshot also has push-button start-stop.

The glove compartment is the only other storage available ...

... And it's actually pretty roomy. One could stash a rain jacket in there, for example.

The RideCommand infotainment system is basic — but good! On a vehicle such as this, I wasn't expecting much, but the audio setup sounded decent, the screen was responsive, and Bluetooth and USB connectivity was on-par with what you'd find in any modern automobile.

There's even GPS navigation, which can display a map and provide turn-by-turn guidance.

The ride-mode selector is doubled in the infotainment system.

So what's the verdict?

I love three-wheelers. They aren't as cool as two-wheeled motorbikes, but they provide easy access to open-air motoring, and the driving/riding experience is much more engaging than what you find in convertible automobiles.

For anybody who dislikes the impracticality of motorcycles but wants to partake of the open-road lifestyle, machines like the Slingshot (the Can-Am Spyder and the Harley-Davidson Freewheeler, to name two) are ideal.

Not for nothing, they also offer aging riders a chance to yank their helmets and biker jackets out of storage to pursue moderately safer riding. With the Slingshot, gearing-up isn't necessary.

The trade-off, of course, is price. The Slingshot R that I tested costs more than an entry-level car or SUV. So, an expensive plaything. But there's nothing wrong with that. Everybody needs a hobby.

No doubt about it, the Slingshot captures attention. I lost count of how many little kids a stopped in their tracks as I tooled around the Jersey suburbs. The last vehicle that provoked such astonishment was the Lamborghini Huracán Performante. If you become a Slingshotter, prepare to be pointed at and asked for photo-ops.

Driving-wise, the Slingshot scratches an itch: on the road, the experience is unexpurgated — you don't have to be constantly vigilant, as you would on a bike, but you do need to remain aware. Highway trips are demanding. And noisy. And exhilarating. The Slingshot R is also fast and torque-y and the power goes to the single back wheel, so the while the two-wheeled front is stable, the back end can get pretty wiggly, especially in Slingshot mode, if you stomp the throttle.

I had iffy springtime Northeast weather to contend with, so I took the Slingshot out only on warm and sunny days; the rest of the time, I parked it in my garage. But the vehicle can handle being rained on, and one could also buy a cover to protect it from the elements. To be honest, however, I think it's a better choice in warm, dry climates. 

The performance is aggressively go-kart-y. This thing will make you a better drive, thanks to its point-and-shoot steering, crisp suspension, and easy access to power. It's insanely fun on curves and into corners. But it's also worthy of short road trips. In fact, the relative comfort was a shocker: I took the Slingshot out for a few hours one day and suffered no ill-effects to my lower back.

Drawback? The design is thoroughly sporty, so if you don't go in for that, the Slingshot might not be your bag. It isn't a throwback, nor is it at all steam-punky. 

It also isn't a motorcycle, in that there aren't any handlebars, you don't throw a leg, and the single wheel takes up the rear. 

But the Slingshot is a absolute blast, and if you're a weekend warrior who wants to carve up a canyon or a country road without having the grapple with a motorcycle's demands — and you don't mind dropping some dollars — the Slingshot is perfect.

Amylin, a pancreatic hormone and neuropeptide, acts principally in the hindbrain to decrease food intake and has been recently shown to act as a neurotrophic factor to control the development of AP->NTS and ARC->PVN axonal fiber outgrowth. Amylin is also able to activate ERK signaling specifically in POMC neurons independently of leptin. To investigate the physiological role of amylin signaling in POMC neurons, the core component of the amylin receptor, calcitonin receptor (CTR) was depleted from POMC neurons using an inducible mouse model. The loss of CTR in POMC neurons leads to increased body weight gain, increased adiposity, and glucose intolerance in male knockout mice, characterized by decreased energy expenditure (EE) and decreased expression of uncoupling protein 1 (UCP1) in brown adipose tissue (BAT). Furthermore, a decreased spontaneous locomotor activity and absent thermogenic reaction to the application of the amylin receptor agonist were observed in male and female mice. Together, these results show a significant physiological impact of amylin/calcitonin signaling in CTR-POMC neurons on energy metabolism and demonstrate the need for sex-specific approaches in obesity research and potentially treatment.

The capacity to process information in conceptual form is a fundamental aspect of human cognition, yet little is known about how this type of information is encoded in the brain. Although the role of sensory and motor cortical areas has been a focus of recent debate, neuroimaging studies of concept representation consistently implicate a network of heteromodal areas that seem to support concept retrieval in general rather than knowledge related to any particular sensory-motor content. We used predictive machine learning on fMRI data to investigate the hypothesis that cortical areas in this "general semantic network" (GSN) encode multimodal information derived from basic sensory-motor processes, possibly functioning as convergence–divergence zones for distributed concept representation. An encoding model based on five conceptual attributes directly related to sensory-motor experience (sound, color, shape, manipulability, and visual motion) was used to predict brain activation patterns associated with individual lexical concepts in a semantic decision task. When the analysis was restricted to voxels in the GSN, the model was able to identify the activation patterns corresponding to individual concrete concepts significantly above chance. In contrast, a model based on five perceptual attributes of the word form performed at chance level. This pattern was reversed when the analysis was restricted to areas involved in the perceptual analysis of written word forms. These results indicate that heteromodal areas involved in semantic processing encode information about the relative importance of different sensory-motor attributes of concepts, possibly by storing particular combinations of sensory and motor features.

SIGNIFICANCE STATEMENT The present study used a predictive encoding model of word semantics to decode conceptual information from neural activity in heteromodal cortical areas. The model is based on five sensory-motor attributes of word meaning (color, shape, sound, visual motion, and manipulability) and encodes the relative importance of each attribute to the meaning of a word. This is the first demonstration that heteromodal areas involved in semantic processing can discriminate between different concepts based on sensory-motor information alone. This finding indicates that the brain represents concepts as multimodal combinations of sensory and motor representations.
