Unveiling the Origins of Human Social Behaviors

New research from Cornell University suggests that the visual system of male fruit flies plays a significant role in their social behaviors, in addition to chemical receptors. By altering the GABARAP/GABAA receptor signaling in the visual feedback neurons of male fruit flies, researchers found that the flies exhibited unexpected courtship behavior towards other males. The study provides insights into the possible origins of differences in human social behaviors and offers a promising avenue for investigating the role of similar genes in the human brain and their contribution to psychiatric conditions such as autism and schizophrenia.

Cracking the Code of Social Interactions

New research challenges the belief that fruit flies rely solely on chemical receptors for social interactions, revealing that their visual system also plays a crucial role. By manipulating the visual feedback neurons in male fruit flies, scientists found that their social inhibitions were altered, leading to courtship between males. This discovery sheds light on the potential origins of differences in human social behaviors, including those seen in individuals with bipolar disorder and autism. Genes similar to those controlling fruit fly visual neurons are found in the human brain, offering insights into the regulation of social behaviors and psychiatric conditions.

Distinct Cerebellar Neurons Impact Motor and Social Behaviors

Two types of neurons in the cerebellum, excitatory glutamatergic neurons in the cerebellar cortex and cerebellar nuclei, play distinct roles in regulating motor and non-motor behaviors during development and adulthood. Silencing these neurons in early postnatal stages caused severe impairments in both motor and social vocalization behavior, but natural molecular transitions later normalized social behaviors with only mild motor deficits persisting in adult mice. The cerebellar cortex neurons control the acquisition of social skills whereas the cerebellar nuclei affect the establishment of motor behaviors, showing that the brain can compensate for some, but not all, perturbations occurring in the developing cerebellum.
