Early-Life Pain May Lead To Obesity Risk, Especially In Females, Neuroscience Institute Study Finds Early-Life Pain May Lead To Obesity Risk, Especially In Females, Neuroscience Institute Study Finds

Inflammatory pain at birth changes how the hippocampus, a part of the brain associated with memory and eating behavior, works later in life, and this pain also causes adult rats to eat more frequently and in larger amounts, according to a study by Georgia State University and the Charlie Norwood VA Medical Center.

In Sex-Changing Fish, Male-Typical Sexual Behavior Associated With Elevated Expression Of Male Sex Hormone Receptors In Muscles

Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to a Georgia State University study. 

Androgen signaling is a critical regulator of male-typical reproductive behavior in vertebrates. This study found androgen receptor expression is also important… more »

Georgia State Neuroscientists Rewire Brain Of One Species To Have Connectivity Of Another

Scientists at Georgia State University have rewired the neural circuit of one species and given it the connections of another species to test a hypothesis about the evolution of neural circuits and behavior. 

Neurons are connected to each other to form networks that underlie behaviors. Drs. Akira Sakurai and Paul Katz of Georgia State’s… more »
