by Shaheen Lakhan in Brain Blogger

Prostate cancer is the leading cancer among American men, but little is actually known about its causes or risk factors.

Androgens are also necessary for the growth and [...]... Read more »

How to Recharge the Batteries in our Brain

by Shaheen Lakhan in Brain Blogger

Imaging the Musical Brain

by Shaheen Lakhan in Brain Blogger

Humans experience pleasure from a variety of stimuli, including food, money, and psychoactive drugs. Such pleasures are largely made possible by a brain chemical called dopamine, which activates what is known as the mesolimbic system — a network of interconnected brain regions that mediate reward. Most often, rewarding stimuli are biologically necessary for survival (such [...]... Read more »

Too Much Information? – Labeling Restaurant Menus

by Shaheen Lakhan in Brain Blogger

Information can be a source of learning; but, when there is too much information, or it is not available in a form that can be easily understood and analyzed by the person for whom it is intended, information can be a burden. Or, too much information can simply be ignored in an over-stimulated society. Such [...]... Read more »

Cartoon – Alcohol and Aggression

by Shaheen Lakhan in Brain Blogger

Judging by all the destruction caused by the test subject, drinking more does make one more aggressive.
