A new study reveals that serotonin and neuropeptide F regulate aggression in fruit flies, similar to their effects on mammals. The findings suggest that the molecular and neural roots for complex social behavior are of ancient evolutionary origin.
Researchers from The Neurosciences Institute and Arizona State University successfully implanted electrodes in monkey brains to decode neural signals controlling arm movements. This breakthrough technology aims to restore movement to individuals with paralyzed arms through a 'neural bypass'.
Researchers used DNA microarrays to analyze 40% of the fruit fly genome and found that genetic changes are the result of many small contributors. The study's findings suggest that human genetic biases may also be caused by small changes in multiple genes.
Researchers have identified two genes that play a crucial role in sleep function, found in both fruit flies and humans. These genes control the internal clock and protect against stress, highlighting the importance of sleep in maintaining overall health.
Researchers at The Neurosciences Institute propose a new hypothesis, the dynamic core hypothesis, suggesting that consciousness arises from the synchronized activity of large populations of neurons in the cerebral cortex. This approach aims to explain two fundamental properties of conscious states: integration and differentiation.
