A method for calculating current source density (CSD) analysis without resorting to recording sites outside the sampling volume.

This article is part of a study on cortical microcircuitry in which flash evoked potentials (FEPs) were recorded from the anesthetized rat visual cortex. The FEPs were subjected to current source density analysis (CSD). One of the limitations of the…

Hyperpolarizing and depolarizing GABAA receptor-mediated dendritic inhibition in area CA1 of the rat hippocampus.

1. gamma-Aminobutyric acidA (GABAA) receptor-mediated inhibition of pyramidal neuron dendrites was studied in area CA1 of the rat hippocampal slice preparation with the use of intracellular and extracellular recording and one-dimensional current…

Roles of inhibition in creating complex auditory responses in the inferior colliculus: facilitated combination-sensitive neurons.

We studied roles of inhibition on temporally sensitive facilitation in combination-sensitive neurons from the mustached bat's inferior colliculus (IC). In these integrative neurons, excitatory responses to best frequency (BF) tones are enhanced by…

Endogenous mGluR activity suppresses GABAergic transmission in avian cochlear nucleus magnocellularis neurons.

GABAergic transmission in the avian cochlear nucleus magnocellularis (NM) of the chick is subject to modulation by gamma-aminobutyric acid type B (GABA(B)) autoreceptors. Here, I investigated modulation of GABAergic transmission in NM by metabotropic…

Construction of a model demonstrating neural pathways and reflex arcs.

Employment opportunities in the future will require higher skills and an understanding of mathematics and science. As a result of the growing number of careers that require solid science and mathematics training, the methods of science education are…

Neural processing of target distance by echolocating bats: functional roles of the auditory midbrain.

Using their biological sonar, bats estimate distance to avoid obstacles and capture moving prey. The primary distance cue is the delay between the bat's emitted echolocation pulse and the return of an echo. The mustached bat's auditory midbrain…

Synaptic plasticity in the hippocampal slice: functional consequences.

There are 3 known forms of synaptic plasticity at CNS synapses: long-term potentiation (LTP) mediated by NMDA receptor activation, LTP mediated by voltage-dependent calcium channel (VDCC) activation, and long-term depression (LTD) mediated by the…

Use of brain slices to study long-term potentiation and depression as examples of synaptic plasticity.

Brain slices have been responsible for the majority of advances in our understanding of the cellular aspects of altered synaptic strength underlying memory, long-term potentiation (LTP) and long-term depression (LTD), and increases and decreases,…

Activation and circuitry of uterine-cervix-related neurons in the lumbosacral dorsal root ganglia and spinal cord at parturition.

Stimulation of the uterine cervix at parturition activates neural circuits involving primary sensory nerves and supraspinally projecting neurons of the lumbosacral spinal cord, resulting in output of hypothalamic neurohormones. Dorsal root ganglia…
