A new study shows that when energy is depleted—such as during a stroke—neurons begin releasing glutamate in abnormal, self-amplifying bursts that can damage nerve cells.Read More

Researchers propose that recognizing emotion is part of forming an overall impression of a person, shaped by cues like clothing, perceived social roles, and personal history. For instance, a facial expression of fear might be interpreted as anger if background context suggests it.Read More

Researchers found that this receptor, when overactivated, suppresses sensory input, potentially explaining the effects of hallucinations from drugs like LSD.Read More

Using the free energy principle, the study highlights that while some information processes of living organisms can be simulated by computers, the causal structure differences between brains and computers may be crucial for consciousness. This approach aims to prevent the inadvertent creation of artificial consciousness and mitigate deception by seemingly conscious AI.Read More
