In the visual system, receptive fields are volumes in visual space. They are smallest in the fovea where they can be a few minutes of arc like a dot on this page, to the whole page. For example, the receptive field of a single photoreceptor is a cone-shaped volume comprising all the visual directions in which light will alter the firing of that cell. Its apex is located in the center of the l… Webb2 Simple cells have narrow, elongated excitatory and inhibitory zones that have a specific axis of orientation . These cells are “ line detectors ”. Their receptive fields can be built from the convergent connections of lateral geniculate nucleus cells. Complex cells have large receptive fields without clear excitatory or inhibitory zones. shuchishin.mp4

Webb20 aug. 2024 · Homeostasis refers to the body's need to reach and maintain a certain state of equilibrium. The term was first coined by a physiologist named Walter Cannon in 1926. More specifically, homeostasis is the body's tendency to monitor and maintain internal states, such as temperature and blood sugar, at fairly constant and stable levels. 1. WebbThe life of cell consists of stages that make up the cell cycle. After a cell is born, it passes through an interphase before it is ready to replicate itself and produce daughter cells. This interphase includes two gap phases (G 1 and G 2 ), as well as an S phase, during which its DNA is replicated in preparation for cell division.

A simple cell in the primary visual cortex is a cell that responds primarily to oriented edges and gratings (bars of particular orientations). These cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. Such cells are tuned to different frequencies and orientations, even with different phase relationships, possibly for extracting disparity (depth) informati… Webb14 feb. 2024 · A synapse is a small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron. It is referred to as the synaptic cleft or synaptic gap. During synaptic transmission, the action potential (an electrical impulse) …
