Summation, which includes both spatial summation and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).
This spatial–temporal decorrelation makes for much more efficient coding. However, there is almost certainly much more going on. Like other areas of the thalamus , particularly other relay nuclei , the LGN likely helps the visual system focus its attention on the most important information.
The central nervous system has two distinct ways of controlling the force produced by a muscle through motor unit recruitment: spatial recruitment and temporal recruitment. Spatial recruitment is the activation of more motor units to produce a greater force.
Anatomy of a multipolar neuron. A neural circuit is a population of neurons interconnected by synapses to carry out ... Connections display temporal and spatial ...
Relieved of the requirement to map the position of an olfactory stimulus in space, the olfactory system employs spatial segregation of sensory input to encode the quality of an odorant. [ 7 ] The topographic map revealed in the olfactory system differs in quality from the orderly representation inherent in the retinotopic, tonotopic, or ...
The spectro-temporal receptive field or spatio-temporal receptive field (STRF) of a neuron represents which types of stimuli excite or inhibit that neuron. [1] " Spectro-temporal" refers most commonly to audition, where the neuron's response depends on frequency versus time, while "spatio-temporal" refers to vision, where the neuron's response depends on spatial location versus time.
The brain contains four main lobes: temporal lobe, parietal lobe, frontal lobe, and the occipital lobe. The temporoparietal junction lies in the region between the temporal and parietal lobes, near the lateral sulcus (Sylvian fissure). Specifically, it is composed of the inferior parietal lobule and the caudal parts of the superior temporal ...
In addition to place cells and grid cells, two further classes of spatial cell have since been identified in the hippocampal formation: head direction cells and boundary cells. As with the memory theory, there is now almost universal agreement that the hippocampal formation plays an important role in spatial coding, but the details are widely ...
