WebComputational models suggest that a post-traumatic inflammatory response could elicit epileptogenic activity by hijacking the astrocyte-mediated excitatory synaptic scaling system (Savin et al., 2009). Similar models also implicate synaptic scaling in the creation of epileptic burst firing within the deafferented cortex (Houweling et al., 2005). WebExcitatory postsynaptic potentials (EPSPs) produced in the motor neurons by the mechanoreceptors decrease in amplitude when the mechanoreceptors are repeatedly stimulated, at least partly accounting for habituation; From: Encyclopedia of Behavioral Neuroscience, 2010 Related terms: Interneuron Action Potential Glutamatergic Spike … the hungry fisherman restaurant https://holistichealersgroup.com
