Tyrosine hydroxylase activity in sympathetic nervous system of rats with streptozocin-induced diabetes.

30 Jul 1989 The activity of tyrosine hydroxylase (TOH), the rate-limiting enzyme in norepinephrine biosynthesis, was measured in selected sympathetic ganglia to develop a quantitative measure of sympathetic autonomic neuropathy in streptozocin-induced diabetic ... Read more...

[Study of the mechanisms of the development of epileptic activity in neuronal networks using a simulation model]

30 Aug 1988 The occurrence of synchronous, self-sustaining seizure activity is one of the basic mechanisms underlying epileptic attacks. Using a mathematical model of neuronal network in various simulation experiments carried out in digital computer the ... Read more...

Auditory brain-stem (ABP) and somatosensory evoked potentials (SEP) in an animal model of a synaptic lesion: elevated plasma barbiturate levels.

30 Aug 1988 Experiments were conducted to determine whether a consistent pattern of auditory nerve brain-stem evoked synaptic lesion model in cats (elevated levels of the lesion model in cats (elevated levels of the barbiturate thiopental). The ABP in response ... Read more...

Technical information about 'Synapses'

Definition: Specialized junctions at which a neuron communicates with a target cell. At classical synapses, a neuron's presynaptic terminal releases a chemical transmitter stored in synaptic vesicles which diffuses across a narrow synaptic cleft and activates receptors on the postsynaptic membrane of the target cell. The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate via direct electrical coupling with ELECTRICAL SYNAPSES. Several other non-synaptic chemical or electric signal transmitting processes occur via extracellular mediated interactions.
