Many of the differences in … WebFeb 5, 2014 · Receptors encode stimulus modality by responding to one form of energy more than any other, and ... Stimulus intensity is encoded in two ways: 1) frequency coding, where the firing rate of sensory neurons increases with increased intensity and 2) population coding, where the number of primary afferents responding increases ...
A sequence, or 'train', of spikes may contain information based on different coding schemes. In some neurons the strength with which an postsynaptic partner responds may depend solely on the 'firing rate', the average number of spikes per unit time (a 'rate code'). At the other end, a complex 'temporal code' is based on the precise timing of single spikes. They may be locked to an externa… WebAug 7, 2024 · Individual Neurons Can Carry Multiple Signals at a Time, Neuroscientists Find. A team of researchers from Duke and Rockefeller Universities has found that individual neurons can encode information about multiple stimuli simultaneously, much the same way electronics like cell phones sort signals by frequency. The findings appear in the journal ...
