Release of neurotransmitters from glia.
There is no question about the fact that astrocytes and other glial cells release neurotransmitters that activate receptors on neurons, glia and vascular cells, and that calcium is an important second messenger regulating the release. This occurs in cell culture, tissue slice and in vivo. Negative results from informative experiments designed to test the mechanism of calcium-dependent neurotran...
متن کاملFrom Computational Theory to Psychology and Neurophysiology
The CNS needs to be understood at four nearly independent levels of description: (1) that at which the nature of a computation is expressed; (2) that at which the algorithms that implement a computation are characterlsed; (3) that at which an algorithm is committed to particular mechanisms; and (4) that at which the mechanisms are realised in hardware. In general, the nature of a computation is...
متن کاملVisual Neurophysiology: Recordings from the Human Primate
Neurophysiological studies in human patients, with experiments of the kind traditionally reserved for monkeys, are beginning to provide valuable insight into the workings of the brain. Taking center stage is the question of which neurons lie at the heart of perception itself.
متن کاملNeurophysiology: Recording from Neurons in Action
Sensory neurons have mostly been studied in fixed animals, but how do they behave when the animal is free to move? A recent study shows that, during locomotor activity, besides there being a general enhancement in responsiveness, the tuning curves of neurons can also change, altering their optimal stimuli.
متن کاملRebuilding Cerebellar Network Computations from Cellular Neurophysiology
This schematic drawing shows the most relevant connections within a cerebellar module. The mossy fibers contact granule cells (GrC) and deep cerebellar nuclei (DCN) cells which, in turn, receive inhibition from the same common set of Purkinje cells (PC). Moreover, the interior olive (IO) cells emit climbing fibers that contact DCN cells and Purkinje cells (PC), which also project to the same DC...
