Pathology - Theories of recovery

change in brain by experiences and memories

"the effects of damage to the brain are determined by extent rather than location of the damage" theory:

neural plasticity: structural formation of new connections which takes days to months

equipotentiallity theory: the neural networks have backups that take over once the main pathways are damaged->

electrical synapses use gap junctions to directly influence membrane potential

injury in the cholinergic modulating system:

electrical synapses are more common than chemical synapses

why are electrical synapses important for the CNS

when brain functions move from damaged to undamaged areas. usually seen in patients who suffered from a stroke

neuron that trasfers impulse/stimulus to another neuron

neural plasticity: physiological formation of new connections which takes minutes to days

synapse that uses a neurotransmitter to change the membrane potential

the size and number of the dendritic spines determine the potential for neural plasticity
