Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.
An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those impulses to other neurons, muscle cells, or glands.
A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. [1] [2] [3] Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting.
Examples of methods include the modelling of neurons, networks and brain systems and theoretical analysis. [38] Computational methods have a wide variety of roles including clarifying experiments, hypothesis testing and generating new insights. These techniques play an increasing role in the advancement of biological psychology. [39]
Olfactory neurons utilize a feedback system from the levels of Ca 2+ ions to activate its adaptation to prolonged smells. Due to the fact that the olfactory signal transduction uses a second messenger transduction system, the mechanism of adaptation includes several factors that mostly include CaMK or calmodulin bound to Ca 2+ ions.
Anatomy of a multipolar neuron. A neural circuit is a population of neurons interconnected by synapses to carry out a specific function when activated. [1] Multiple neural circuits interconnect with one another to form large scale brain networks.
A hypercomplex cell (currently called an end-stopped cell) is a type of visual processing neuron in the mammalian cerebral cortex.Initially discovered by David Hubel and Torsten Wiesel in 1965, hypercomplex cells are defined by the property of end-stopping, which is a decrease in firing strength with increasingly larger stimuli.
The numbers of neurons born in the human adult hippocampus remains controversial; some studies have reported that in adult humans about 700 new neurons are added in the hippocampus every day, [14] while more recent studies show that adult hippocampal neurogenesis does not exist in humans, or, if it does, it is at undetectable levels.
