Cognition and Behavior Report

Name	Perception
Description	Perception is the process of attaining awareness or understanding of the environment by organizing and interpreting sensory information. All perception involves signals in the nervous system, which in turn result from physical stimulation of the sense organs. Perception is not the passive receipt of these signals, but can be shaped by learning, memory and expectation. Perception involves these "top-down" effects as well as the "bottom-up" process of processing sensory input.

poorer performance on tests involving visuospatial ability	Baldwin, 2004	patients and normal controls		Patients who did not respond to antidepressant monotherapy h...... Patients who did not respond to antidepressant monotherapy had significantly poorer performance than controls on tests involving visuospatial ability, language, word recognition and tests of executive function, whereas there were no differences between control subjects and responders.

impaired performance in orienting		CACNA1C(CACNA1C)	gene	Thimm, 2011	normal people		Risk allele carriers showed impaired performance in alerting...... Risk allele carriers showed impaired performance in alerting and orienting in addition to reduced neural activity in the right inferior parietal lobule [Brodmann area (BA) 40] during orienting and in the medial frontal gyrus (BA 8) during executive control of attention.

abnormal perceptual processing		N200(negative activity in the 157-210 ms section of the waveform)	neurobiological system	Pelosi, 2000	patients and normal controls		Surface negative activity in the 157-210 ms section of the w...... Surface negative activity in the 157-210 ms section of the waveform was reduced for all levels of memory load, suggesting abnormal sensory/perceptual processing in the modality-specific association cortices.

impaired spatial navigation		anterior hippocampus(anterior hippocampus)	brain morphology and function	Cornwell, 2010	patients and normal controls		Depressed patients showed impaired spatial navigation. Dysfu...... Depressed patients showed impaired spatial navigation. Dysfunction of right anterior hippocampus and parahippocampal cortices may underlie this deficit and stem from structural abnormalities commonly found in depressed patients. More...

Dysfu...... Depressed patients showed impaired spatial navigation. Dysfunction of right anterior hippocampus and parahippocampal cortices may underlie this deficit and stem from structural abnormalities commonly found in depressed patients. More...

2. User can drag the nodes to rearrange the layout of the network. Click the node will enter the report page of the node. Right-click will show also the menus to link to the report page of the node and remove the node and related edges. Hover the node will show the level of the node and hover the edge will show the evidence/description of the edge.
