Wistar rats with different levels of resistance to emotional stress (ES) were subjected to stress and brain sections stained with Nissl cresyl violet were used for quantitative analysis of the structural organization of neurons in layer V of the sensorimotor cortex. Some animals received delta sleep-inducing peptide (DSIP) 1 h before stress. Control(More)
Wistar rats behaviorally active in the open field test (resistant to emotional stress) are characterized by polymorphism of neurons in layer V of the sensorimotor cortex and the presence of hyperchromatic cells, which probably determines resistance to emotional stress in these rats. Atrophy of hyperchromatic neurons reflecting transient inhibition of cell(More)

A study of the human and animal bra in affected by var ious local les ions showed that des t ruc t ive changes in the CNS are followed by r e p a i r p r o c e s s e s a imed at r e s to r ing the dis turbed functions. The r e p a i r p r o c e s s e s were manifes ted by hyper t rophy of single neut rons and of glial e l ement s , the appearance of bulbs(More)
Changes in neurons were studied during motor excitation induced by amphetamine. At the time of maximal intensity of amphetamine stimulation after administrat ion of small (1 mg/ kg) and average (2.5 mg/kg) doses the nuclei and bodies in subcort ical brain regions r ich in catecholamines (caudate nucleus, dorsomedial nucleus of the hypothalamus) were inc(More)
The formation of trace rhythm assimilation (an analog of the conditioned reflex to time) by neurons of the sensorimotor cortex in response to prolonged (10–20 min) electrodermal stimulation of an extremity at a frequency of 0.5–1 or 2 Hz was investigated in awake adult (5–7 months), old (54–65 months), and very old (66–85 months) rabbits. The data of the(More)
