Abstract

Conspecifics are potential mates, and can be the most dangerous threats. With conspecifics we engage in complex social interactions. Therefore, it is important to rapidly detect the presence of conspecifics in a scene. Images of humans attract attention, and do so already in 9-months-old infants, showing that the distinction between conspecifics and other animals emerges early in development. However, despite a wealth of evidence on the behavioral differences between the processing of conspecifics and other animals, the neural mechanisms that underlie the recognition of conspecifics remain unknown. In this experiment, we used recursive feature elimination to individuate brain regions that show selective effects for the faces of conspecifics, individuating reliable conspecific effects in the right ventrolateral prefrontal cortex (vlPFC). Consistent with the importance of conspecifics recognition for reorienting attention and for social cognition, this region shows functional connectivity with the temporo-parietal junction (TPJ), implicated in reorienting attention and in the attribution of mental states to others. Our results suggest that the right vlPFC plays an important role for the recognition of conspecifics and may functio...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.
