Chronic testosterone treatment impairs vocal learning in male zebra finches during a restricted period of development.
To study the effects of chronic exposure to testosterone on song behavior development, we administered various amounts of testosterone to juvenile male zebra finches during different periods of song acquisition. We report that testosterone exposure during development profoundly impairs song learning in juvenile males. The effects of the hormone do not seem to be dose related but vary according ...
متن کاملInduced cell death in a thalamic nucleus during a restricted period of zebra finch vocal development.
A discrete network of forebrain nuclei underlies vocal learning and production in male zebra finches. Three nuclei within this network form a neural pathway that is particularly important for vocal learning in juveniles: area X of the avian striatum projects to the medial dorsolateral nucleus of the anterior thalamus (DLM), which in turn projects to the lateral magnocellular nucleus of the ante...
متن کاملSensitive period for sensorimotor integration during vocal motor learning.
Sensory experience during sensitive periods in development may direct the organization of neural substrates, thereby permanently influencing subsequent adult behavior. We report a sensitive period during the imitative motor learning phase of sensorimotor integration in birdsong development. By temporarily and reversibly blocking efference to the vocal muscles, we disrupted vocal motor practice ...
متن کاملThe effect of morphine consumption by mother on brain development of rat offspring during lactation period
According to some studies, the number of addicted females in reproductive ages has been increased. The present study was designed to investigate the effect of oral morphine consumption on the development of CNS and body growth in rats. For this purpose, female Sprauge-Dawley rats were divided into control and experimental groups (20 animals in each group). Maintenance dose of morphine (0/4 mg/m...
