Intracellular recording and staining of cat's lateral geniculate neurons. 1978

T Ogawa, and T Takimori, and Y Takahashi

Intracellular staining with recording micropipettes filled with a Procion yellow solution was attempted on 11 lateral geniculate neurons of chloralose-anesthetized cats for the purpose of correlating electrophysiologically identified cell types with morphologically identified cell types. Five neurons were successfully stained: one was located in lamina A and the others in lamina A1. They were all identified as P-cells on the basis of their responsiveness to electrical stimulation of optic disc, optic chiasm and visual cortex. The conduction velocities and synaptic delays for specific optic nerve fibers concerned with these P-cells were estimated from the relationship between latency and conduction distance. Intracellular staining has revealed that a neuron located in lamina A and three of four neurons located in lamina A1 had multipolar configuration, with their main dendrites oriented parallel to the plane of the laminae; while one neuron located in lamina A1 had a configuration similar to that of a class II-type neuron described by Guillery in his Golgi preparations. In these experiments no neurons located in lamina B, central interlaminar nucleus and medial interlaminar nucleus were stained. No interneurons were obtained, either.

UI	MeSH Term	Description	Entries
D007395	Interneurons	Most generally any NEURONS which are not motor or sensory. Interneurons may also refer to neurons whose AXONS remain within a particular brain region in contrast to projection neurons, which have axons projecting to other brain regions.	Intercalated Neurons,Intercalated Neuron,Interneuron,Neuron, Intercalated,Neurons, Intercalated
D008564	Membrane Potentials	The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).

D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D009897	Optic Chiasm	The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.

D009898	Optic Disk	The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D005829	Geniculate Bodies	Part of the DIENCEPHALON inferior to the caudal end of the dorsal THALAMUS. Includes the lateral geniculate body which relays visual impulses from the OPTIC TRACT to the calcarine cortex, and the medial geniculate body which relays auditory impulses from the lateral lemniscus to the AUDITORY CORTEX.
