Разработка поведенческого бокса для оценки предимпульсного торможения и нейронной активности в моделях психиатрических животных

Overview

This protocol outlines a microcontroller-based behavioral box designed to assess prepulse inhibition (PPI) in socially isolated rats, aiming to evaluate sensory gating deficits related to psychiatric disorders such as schizophrenia. By synchronizing accelerometer data with neuronal activity, this study seeks to advance neurophysiology research focused on understanding behavioral disorders.
