Dendritic Spine Density is Increased in Arcadlin-deleted Mouse Hippocampus.

The neural network undergoes remodeling in response to neural activity and interventions, such as antidepressants. Cell adhesion molecules that link pre- and post-synaptic membranes are responsible not only for the establishment of the neural circuitry, but also for the modulation of the strength of each synaptic connection. Among the various classes of synaptic cell adhesion molecules, a non-clustered protocadherin, Arcadlin/Paraxial protocadherin/Protocadherin-8 (Acad), is unique in that it is induced quickly in response to neural activity.

A Multimodal Emotional Human-Robot Interaction Architecture for Social Robots Engaged in Bidirectional Communication.

For social robots to effectively engage in human-robot interaction (HRI), they need to be able to interpret human affective cues and to respond appropriately via display of their own emotional behavior. In this article, we present a novel multimodal emotional HRI architecture to promote natural and engaging bidirectional emotional communications between a social robot and a human user. User affect is detected using a unique combination of body language and vocal intonation, and multimodal classification is performed using a Bayesian Network.
