Parietal Lobe: Function, Location, and Damage Explained
What Is the Parietal Lobe? The parietal lobe sits under the top and back of your skull, between your ears and the back of your head. Its main job is taking in feelings from your body — touch, pressure, where your limbs are in space — and combining that with what you see, so your…

Frontal Lobe: Function, Location, and What Happens When It’s Damaged
What Is the Frontal Lobe? The frontal lobe is the front section of the brain, sitting roughly behind your forehead. It does two very different jobs at once: it moves your body on purpose, and it helps you plan, judge situations, and hold back impulses you’d regret acting on. Every person has two, one behind…

Four Lobes of the Brain: Location, Function, and Anatomy
What Are the Four Lobes of the Brain? The surface of your brain is divided into four regions on each side, called lobes: the frontal lobe (front), parietal lobe (top-back), temporal lobe (side, near the ears), and occipital lobe (very back). Each one specializes in certain jobs, the way departments in a company do, but…

How Does the Brain Control the Autonomic Nervous System?
Learn how the forebrain, hypothalamus, brainstem, spinal cord, and visceral feedback coordinate sympathetic, parasympathetic, and enteric functions.

How Does the Brain Control Sleep?
Learn how circadian timing, homeostatic sleep pressure, and distributed neural circuits coordinate wakefulness, NREM sleep, and REM sleep.

How Does the Brain Form Habits?
Learn how repeated behavior can shift from goal-directed to habitual control, how corticostriatal circuits and dopamine contribute, and why “66 days” is not a rule.
