Intracerebroventricular injection of L-aspartic acid and L-asparagine induces sedative effects under an acute stressful condition in neonatal chicks.

The present study was conducted to clarify the central functions of L-aspartic acid (Asp) and L-asparagine (Asn) during an acute stressful condition in chicks. Intracerebroventricular (i.c.

Central L-cysteine induces sleep, and D-cysteine induces sleep and abnormal behavior during acute stress in neonatal chicks.

L-cysteine (L-Cys) is a non-essential and glycogenic amino acid. Previously, we reported that the intracerebroventricular (i.c.

Central administration of dipeptides, beta-alanyl-BCAAs, induces hyperactivity in chicks.

Background: Carnosine (beta-alanyl-L-histidine) is a putative neurotransmitter and has a possible role in neuron-glia cell interactions. Previously, we reported that carnosine induced hyperactivity in chicks when intracerebroventricularly (i.c.

Intracerebroventricular injection of L-serine analogs and derivatives induces sedative and hypnotic effects under an acute stressful condition in neonatal chicks.

Four experiments were conducted to clarify the central functions of L-serine and its analogs on an acute stressful condition. Intracerebroventricular (i.c.
