Sleep and wakefulness in the southern sea lion
We recorded an electroencephalogram from the two hemispheres, a neck musculature electromyogram, an electrooculogram, and respiratory acts during sleep and wakefulness on land in three 1-year-old seaExpand
Sleep in an Amazonian manatee,Trichechus inunguis
For the first time, sleep was studied in a representative of the order of Sirenia. Slow wave sleep occupied 27%, and paradoxical sleep 1% of the total recording time in the AmazonianExpand
Unilateral EEG activation during sleep in the Cape fur seal, Arctocehalus pusillus
Sleep and wakefulness on the land were studied electrophysiologically in one adult female Cape fur seal (Arctocephalus pusillus). In two 24-h sessions, slow-wave sleep and paradoxical sleep averagedExpand
[Functional characteristics of the orientation-selective neurons in the frontal visual field of the striate cortex in the baronduki].
The extracellular activity of 150 neurons (field 17) from binocular region of the visual cortex in the Siberian chipmunk was investigated. 65% of neurons proved to be selective to orientation andExpand
[The chromatic characteristics of neuronal receptor fields in the visual cortex of the baronduki].
39 orientation-selective neurons and 25 neurons responding to total illumination of the receptive field were investigated by exposing to achromatic and chromatic stimuli. Switching on and off of theExpand
Functional characteristics of directionally tuned neurons in the frontal visual field of the chipmunk striate cortex
Research was performed on the intracellular activity of 150 neurons belonging to area 17 of the binocular region of the chipmunk visual cortex, showing that 65% were directionally selective and tunedExpand
