New Insight into How the Brain ‘Learns’ Cocaine Addiction - Researchers used different types of experiments in order to piece together how dopamine released in response to cocaine works with mGluR5 and immediate early genes to switch cells into synapse-strengthening mode. This image shows the exaggerated dopamine release in response to cocaine. More at NeuroscienceNews.com.
Male brains have more connections within each hemisphere, while female brains are more interconnected between hemispheres. The researchers found that in men, fiber pathways run back and forth within each hemisphere, while in women they tend to zig-zag between the left, or “logical,” and right, or “creative,” sides of the brain. Female brains seem to have a stronger connections between their logical and intuitive parts
