GABAergic neurons and GABA_A receptors (GABA_ARs) are critical elements of almost all neuronal circuits. Most GABA_ARs of the CNS are heteropentameric ion channels composed of two α, two β, and one subunits. These receptors serve as important drug targets for benzodiazepine (BDZ) site agonists, which potentiate the action of GABA at GABA_ARs. Most GABA_AR classifications rely on the heterogeneity of the α subunit (α1–α6) included in the receptor complex. Heterogeneity of the subunits (1–3), which mediate synaptic clustering of GABA_ARs and contribute, together with α subunits, to the benzodiazepine (BDZ) binding site, has gained less attention, mainly because 2 subunits greatly outnumber the other subunits in most brain regions. Here, we have investigated a potential role of non-2 GABA_ARs in neural circuits of the spinal dorsal horn, a key site of nociceptive processing. Female and male mice were studied. We demonstrate that besides 2 subunits, 1 subunits are significantly expressed in the spinal dorsal horn, especially in its superficial layers. Unlike global 2 subunit deletion, which is lethal, spinal cord-specific loss of 2 subunits was well tolerated. GABA_AR clustering in the superficial dorsal horn remained largely unaffected and antihyperalgesic actions of HZ-166, a nonsedative BDZ site agonist, were partially retained. Our results thus suggest that the superficial dorsal horn harbors functionally relevant amounts of 1 subunits that support the synaptic clustering of GABA_ARs in this site. They further suggest that 1 containing GABA_ARs contribute to the spinal control of nociceptive information flow.

A method for providing error detection and/or correction to an array of storage cells includes determining a sensitive direction and an insensitive direction of the storage cells and adding a first error control mechanism to the array of storage cells in the insensitive direction. The method also includes adding a second error control mechanism to the array of storage cells in the sensitive direction. The second error control mechanism has a higher Hamming distance than the first error control mechanism.

A method of asymmetric asynchronous decoupling of capacitors in an integrated circuit design is provided for faster simulation by circuit simulators, e.g. FastSPICE circuit simulators. This method includes removing a coupling capacitor from a list, which includes coupling capacitors that capacitively couple two nets in the design. The two nets have capacitances C1 and C2, and at least one of capacitances C1 and C2 exceeds a threshold. The coupling capacitor has capacitance Cc. When coupling capacitance Cc is low and only one of capacitances C1 and C2 has a low capacitance, then a forward capacitance can be used at whichever of the two nets has the low capacitance and a lump capacitance can be used at the other net for simulation. When coupling capacitance Cc is low and both of capacitances C1 and C2 have high capacitances, then lump capacitances can be used at the two nets for the simulation.

A method and device for synchronizing the time between at least two integrated circuits (201, 202), which receive the same pulse signal. In the integrated circuits (201, 202) a counter (204, 206) is used to count the number of pulses in the received pulse signal to synchronize the common time between said integrated circuits.

This invention is directed to a polymer thick film UV-curable thermoformable dielectric composition. Dielectrics made from the composition can be used in various electronic applications to protect electrical elements and particularly to insulate and protect both the conductive thermoformable silver and the polycarbonate substrate below it in capacitive switch applications. The thermoformed capacitive switch circuit may be subsequently subjected to an injection molding process.

The mother board mounts electronic circuits that electrically communicate with the optical transmitter optical subassembly and the receiver optical subassembly. The daughter board mounts other electronic circuits that electrically communicate with the optical transmitter optical subassembly and the receiver optical subassembly. The daughter board has an extra area mounting a portion of the other electronic circuits. The housing defines a space for installing the optical transmitter optical subassembly, the receiver optical subassembly, the mother board, and the daughter board. The extra area is disposed outside the space.
