[Sensory characteristics of the cortical input of the hippocampus, the dentate fascia].

Investigation of sensory reactions of the neurones of the dentate fascia was performed in unanaesthetized rabbits. Spontaneous activity usually consisted of long aperiodic high-frequency bursts with silent periods between them. Multimodal convergence was observed in 76% of records.

[Sensory characteristics of the cortical input to the hippocampus: the entorhinal cortex].

Sensory reactions of neurones in the medial entorhinal area were investigated in unanaesthetized rabbits. 54% of the units were multimodal. Different stimuli evoked various response patterns with complex on-off components.

[Clinico-morphologic characteristics of periodic disease].

The article deals with clinico-anatomical characteristics of two observations over periodical disease. Peculiar features of the developing in this case of genetic amyloidosis, which is considered as a disease of accumulation, are analysed.
