Intro Neuroscience I — Fall 2026

Cellular + molecular foundations of the nervous system: anatomy and function of neurons, synaptic communication, and how circuits perceive sensory information. Chivero's research lens — microglia, neuroinflammation, NLRP3, HIV-Tat — will surface in regulation + glial unit examples.

Quick start

Online async tips

Chivero rates 4.7/5 on RMP — clear, kind, organized — but reviews flag the course as "extremely difficult, lots of material packed into one semester." Pace yourself: don't cram. Use Mastery 4-5×/wk and watch the matching MIT OCW 9.01 lecture (taught by Bear, the textbook author!).
