This might be partly because animals often have difficulty promptly shifting their cognitive sets under experimental conditions (Asaad et al., 2000; Ma ...

... However, animals and humans with basal ganglia dysfunctions show deficits that may not simply be classified as movement disorders. For example, animals with large lesions in the striatum may ignore a moving object or obsessively follow it (Denny-Brown, 1962). Patients with Parkinson’s disease may have ...

... GDNF-mediated stimulation of the p42/p44 MAPK pathway promotes the arborization, but not the maturation, of GABA- and calbindin-positive striatal neurons We studied whether GDNF induces GABA and calbindin phenotypes, and the differentiation of these neuronal populations. The number of GABA-positive ...

Responses to sound by tonically active neurons (TANs), a class of neurons in the primate striatum, were recorded through a tungsten wire electrode during the application of either D1- or D2-class DA receptor antagonists (total volume õ1 ml, at a rate of 1 ml/5– 10 min). Application of the D2-class a ...

We collected antisera to different biogenic amines from various suppliers (listed below) and tested them primarily for their staining of mono-aminergic neurons in the nervous system of the beetle (Table 1.). It appeared that the antisera to serotonin were among the few staining neurons in the brain. ...

Neural coding

Neural coding is a neuroscience-related field concerned with characterizing the relationship between the stimulus and the individual or ensemble neuronal responses and the relationship among the electrical activity of the neurons in the ensemble. Based on the theory thatsensory and other information is represented in the brain by networks of neurons, it is thought that neurons can encode both digital and analog information.
