Presynaptic inhibition: primary afferent depolarization in crayfish neurons.
Inhibition of transmission between tactile sensory neurons and interneurons in the crayfish was investigated by intracellular recording int the presynaptic processes. Inhibition is correlated with a depolarization of the presynaptic process, as in the mammalian spinal cord; the depolarization is accompanied by a conductance increase, and is mediated by interneurons that can be excited by a vari...
متن کاملPrimary afferent depolarization and frequency processing in auditory afferents.
Presynaptic inhibition is a widespread mechanism modulating the efficiency of synaptic transmission and in sensory pathways is coupled to primary afferent depolarizations. Axonal terminals of bush-cricket auditory afferents received 2-5 mV graded depolarizing inputs, which reduced the amplitude of invading spikes and indicated presynaptic inhibition. These inputs were linked to a picrotoxin-sen...
متن کاملPrimary afferent depolarization: direct evidence in the trigeminal system.
Sensory inputs carried by the peripheral nerve fibers can be regulated at the central terminals of the fibers. Both intracellulad, la,17 and extracellutar 12,15,21,25 recordings at the levels of the spinal cord and dorsal column nuclei have provided evidence for modification of afferent impulses. However, in the trigeminal system only extracellular recordings, which provide indirect evidence of...
متن کاملP11: Assess the Electrophysiological Activity of Olfactory Bulb in the Animal Model of PTSD and its Relationship with Neuroinflammation in the Olfactory Bulb
Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event - either experiencing it or witnessing it. In addition to the relationship between PTSD and neuroinflammation, research indicates that olfactory bulb are effective in anxiety disorders. The aim of this study was to assess the electrophysiological activity of olfactory bulb in the animal mod...
متن کاملCircuit formation and function in the olfactory bulb of mice with reduced spontaneous afferent activity.
The type of neuronal activity required for circuit development is a matter of significant debate. We addressed this issue by analyzing the topographic organization of the olfactory bulb in transgenic mice engineered to have very little afferent spontaneous activity due to the overexpression of the inwardly rectifying potassium channel Kir2.1 in the olfactory sensory neurons (Kir2.1 mice). In th...
