This page serves as an introduction to Functional Neuroimaging
I will mainly focus on a single imaging technique:
functional Magnectic Resonance Imaging

Functional MRI is based on the increase in blood flow to the
local vasculature that accompanies neural activity in the brain

This results in a corresponding local reduction in deoxyhemoglobin.

Since deoxyhemoglobin is paramagnetic, it alters
the magnetic resonance image signal [ more... ]

Simple questions

A newborn foal is capable of taking its first steps within a single hour of its birth
whereas most children take their first steps between 11 and 14 months.
Popular science wants us to believe that this is due to the length of the foals legs.
Can Neuroscience provide a more convincing answer?
