It is suggested that aesthetic experience is a function of the interaction between top-down, intentional orientation of attention and the bottom-up perceptual facilitation of image construction. [23] In other words, because untrained persons automatically apply the object-identification habit to viewing artworks, top-down control to reduce this ...

Currently, single-unit recordings provide the most precise recordings from a single neuron. A single unit is defined as a single, firing neuron whose spike potentials are distinctly isolated by a recording microelectrode. [3] The ability to record signals from neurons is centered around the electric current flow through the neuron.
With few exceptions, each neuron in the brain releases the same chemical neurotransmitter, or combination of neurotransmitters, at all the synaptic connections it makes with other neurons; this rule is known as Dale's principle. [8] Thus, a neuron can be characterized by the neurotransmitters that it releases.
A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.They are located in the brain and spinal cord and help to receive and conduct impulses.
The focus of this article is a comprehensive view of modeling a neural network (technically neuronal network based on neuron model). Once an approach based on the perspective and connectivity is chosen, the models are developed at microscopic (ion and neuron), mesoscopic (functional or population), or macroscopic (system) levels.
A command neuron is a special type of identified neuron, defined as a neuron that is capable of driving a specific behavior individually. [37] Such neurons appear most commonly in the fast escape systems of various species—the squid giant axon and squid giant synapse , used for pioneering experiments in neurophysiology because of their ...
