Moreover, many vulnerable neurons were interconnected in a common neuronal circuit. And … the researchers also found that specifically vulnerable inhibitory neuron subtypes identified in a previously study …

… MIT neuroscientist Kay Tye found specific populations of neurons that assign good or bad feelings , or “valence,” to … how valence-processing circuitry is organized and how key neurons in those circuits interact with others. What they … their association with negative valence, had a very strong inhibitory effect on neighbors, while nucleus accumbens …

… the chance to better understand how different kinds of neurons are contributing to behavior, perception and memory, … measures track the rapid voltage changes, or spikes, that neurons exhibit as they communicate in circuits, a phenomenon … from electrophysiology whether a neuron was excitatory or inhibitory. That’s because they only analyzed the difference …

… now shown that they affect not only the molecular state of neurons, but also the brain’s microglia immune cells, … stimulation is how it affects the electrical activity of neurons and how pervasively. Studies indicate that inhibitory “interneurons” are especially affected, though, …
