Cellular neuroscience is a branch of neuroscience concerned with the study of neurons at a ... For example, Schwann cells, which ... When there is a change in voltage ...
In neuroscience, synaptic plasticity is the ability of synapses to strengthen or weaken over time, in response to increases or decreases in their activity. [1] Since memories are postulated to be represented by vastly interconnected neural circuits in the brain , synaptic plasticity is one of the important neurochemical foundations of learning ...
Hebbian theory is a neuropsychological theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell. It is an attempt to explain synaptic plasticity , the adaptation of brain neurons during the learning process.
In neuroscience, the critical brain hypothesis states that certain biological neuronal networks work near phase transitions. [ 1 ] [ 2 ] [ 3 ] Experimental recordings from large groups of neurons have shown bursts of activity, so-called neuronal avalanches, with sizes that follow a power law distribution.
Neuron theory is an example of consilience where low level theories are absorbed into higher level theories that explain the base data as part of higher order structure. As a result, the neuron doctrine has multiple elements, each of which were the subject of low level theories, debate, and primary data collection.
It is one of several phenomena underlying synaptic plasticity, the ability of chemical synapses to change their strength. As memories are thought to be encoded by modification of synaptic strength, [3] LTP is widely considered one of the major cellular mechanisms that underlies learning and memory. [2] [3]
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject covers topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics and epigenetics on neuronal development, and the molecular basis for neuroplasticity and ...
An example of this phenomenon is when a ball appears to be getting smaller and smaller, the mind will then infer that the ball is moving away from them. In the 1890s, psychologist George M. Stratton conducted experiments in which he tested the theory of perceptual adaptation.
