Bone conducted responses in the neonatal rat auditory cortex.

Rats are born deaf and start hearing at the end of the second postnatal week, when the ear canals open and low-intensity sounds start to evoke responses in the auditory cortex. Here, using μECoG electrode arrays and intracortical silicon probe recordings, we found that bone-conducted (BC) sounds evoked biphasic responses in the auditory cortex starting from postnatal day (P) 8. The initial phase of these responses, generated by thalamocortical input, was followed by intracortical propagation within supragranular layers.

[The efficacy and safety of teraligen in patients with brain ischemia, stages I and II, and psychoautonomic syndrome].

Objective: To assess the efficacy and safety of teraligen in patients with psychoautonomic syndrome comorbid to brain ischemia.

Material And Methods: Forty-five patients, aged from 42 to 65 years (mean age 56 years), diagnosed with brain ischemia, stages I and II, with the signs of psychoautonomic syndrome were examined. Thirty-five patients received teraligen in the daily dose of 15 mg.
