Phase IFoundation

Background

Overview

Highlights India's scientific research capabilities, the importance of basic science for translational medicine, potential for indigenous drug development, and advancements in understanding complex biological processes.

Neuroscience research, a rapidly evolving field, focuses on understanding the structure and function of the nervous system, including the intricate brain circuits that govern sensation, emotion, and behavior. Discoveries in this area are crucial for developing targeted therapies for neurological disorders and mitigating side effects of medical treatments.

Phase IIStatic core

Facts & tables

Key facts

Research Focus

Identifying specific neural pathways and their changes in response to medical treatments or diseases.

Key Discovery

A circuit involving the lateral parabrachial nucleus and parafascicular thalamus linked to chronic cold allodynia.

Methodology

Utilizes invasive experimentation on animal models (e.g., mice) to trace and manipulate neural connections.

Future Implications

Provides targets for pharmacological interventions to reverse chronic pain and potentially other neurological conditions.
