[Effect of variations of the geomagnetic field and solar activity on human physiological indicators].

The influence of changes in solar and geomagnetic activity on physiological parameters of man (EEG, pulse beat, rate of sensomotor reaction and the pressure in the period of spring equinox (10.02-10.04.

[The interrelationship of pain and temperature reception in human skin].

Local cooling (14-16 degrees C) and warming (40-42 degrees C) of different crus areas or healthy volunteers have been studied for their effect on pain sensitivity. The latter was estimated by means of the tibialis anterior flexor reflex (FR) and EMC-recording. It was established that changes in FR parameters depended not on the thermostimulus modality, but on its position.

[Features of projections of afferent fibers of the ventral roots to neurons of the dorsal horn of the spinal cord in the cat].

Some peculiarities of afferent effects from ventral roots on the dorsal horn neurons were investigated in acute experiments on cats. Convergence of afferents from ventral and dorsal roots on the same neurons was shown. Excitation of some ventral root afferents caused inhibition in investigated neurons.
