Jerusalem, Feb 10 (NationPress) A group of Israeli scientists have unveiled the brain mechanisms that play a role in identifying the emotional states of others, which could lead to new treatments for social disorders like autism.

Autism is a neurodevelopmental condition marked by ongoing difficulties in social communication and interaction. Individuals with this disorder frequently exhibit limited interests and engage in repetitive behaviors.

The research, featured in Current Biology, emphasized the significance of the brain's medial prefrontal cortex (mPFC) in emotional recognition and behavior, as reported by the Xinhua news agency. Recognizing emotions is essential for empathy, enabling individuals to connect and respond to others appropriately.

For those on the autism spectrum, this ability is often compromised, leading to challenges in social interactions. To delve into the underlying neural mechanisms, the researchers from the University of Haifa conducted experiments using mice.

Utilizing cutting-edge methods like genetic modifications and real-time neural observation, the team investigated how neurons in the prelimbic region of the mPFC reacted to the emotional states of other mice. They discovered that these neurons responded differently to stressed versus calm mice.

The mice demonstrated a tendency to approach stressed mice, suggesting a reaction based on emotional states. However, when the neural activity in the mPFC was disrupted, the mice lost their ability to differentiate between these emotional states.

This indicates that neural activity in the mPFC is vital for recognizing emotions and shaping social behaviors, such as the decision to approach or avoid others based on their emotional conditions.

The researchers hypothesize that abnormal neural activity in this region could shed light on the challenges with emotional recognition and social behaviors observed in autism.

The next phase involves studying mice with autism-associated genetic mutations to investigate how alterations in neural activity influence their behaviors, as stated by the researchers.
