Flashcards do conjunto (23)
- 1VISUAL RECEIVING AREAStriate cortex
- 2IPSILATERAL EYEEye on the same side of the body as the LGN (Lateral Geniculate Nucleus)
- 3CONTRALATERAL EYEEye on the opposite side of the body from the LGN
- 4SIMPLE CORTICAL CELLSCells with side-by-side receptive fields
- 5END-STOPPED CELLSCells that fire to moving lines of a specific length or to moving corners or angles
- 6FEATURE DETECTORSFeatures of the stimulus
- 7SELECTIVE ADAPTATIONIf the neurons fire for long enough, they become fatigue or adapt; which can cause neuron´s firing rate to decrease or either the neuron firing less when that stimulus is immediately presented again
- 8GRATING´S STIMULIAlternating bars
- 9GRATING´S CONTRAST THRESHOLDDifference in intensity at which the bars can just barely be seen
- 10SELECTIVE REARINGIf an animal is reared in an environment that contains only certain types of stimuli, then neurons that respond to these stimuli will become more prevalent
- 11NEURAL PLASTICITY/ EXPERIENCE-DEPENDENT PLASTICITYIdea that the response properties of neurons can be shaped by perceptual experience
- 12BRAIN IMAGINGNumber of techniques that result in images that show which areas of the brain are active
- 13OCULAR DOMINANCEPreferential response to one eye
- 14CORTEXSeries of columns that alternate in ocular dominance in a left-right-left-right pattern
- 15HYPERCOLUMNSCombination of all three types of columns
- 16ABLATIONDestruction or removal of tissue in the nervous system
- 17FEEDBACK"Backward" flow of information.
Provides information from high centers that influence the signals flowing into the system - 18DISSOCIATIONSSituations in which one function is absent while another function is present
- 19MODULESpecialized structure to process information about a particular type of stimulus
- 20FUSIFORM FACE AREA (FFA)Area specialized to respond to faces.
Located in the fusiform gyrus on the underside of the brain directly below the IT cortex - 21PROSOPAGNOSIADifficulty recognizing the faces of familiar people
- 22PARAHIPPOCAMPAL PLACE AREA (PPA)Important information about spatial layout
- 23EXSTRASTRIATE BODY AREA (EBA)Area activated by pictures of bodies and parts of bodies
