Suppressive Modulation of the Chick Forebrain Network for Imprinting by Thyroid Hormone: An Study.

The thyroid hormone 3,5,3'-triiodothyronine (T) is considered to act acutely in the chick forebrain because focal infusion of T to the intermediate medial mesopallium (IMM) causes 4 to 6-day-old hatchlings to become imprintable approximately 30 min after the infusion. To understand the mechanism of this acute T action, we examined synaptic responses of IMM neurons in slice preparations . Extracellular field potential responses to local electrical stimulation were pharmacologically dissociated to synaptic components mediated by AMPA and NMDA receptors, as well as GABA-A and -B receptors.

Human brain activity reflecting facial attractiveness from skin reflection.

Facial attraction has a great influence on our daily social interactions. Previous studies have mainly focused on the attraction from facial shape and expression. We recently found that faces with radiant skin appear to be more attractive than those with oily-shiny or matte skin.

Facial radiance influences facial attractiveness and affective impressions of faces.

Objective: Facial attractiveness has been reported to be influenced by visual features such as facial shape and the colour and texture of the skin. However, no empirical studies have examined the effects of facial skin radiance on facial attractiveness. The present study investigated whether types of skin reflection (i.
