Modulation of perineuronal nets and parvalbumin with developmental song learning.

12 Oct 2009 Neural circuits and behavior are shaped during developmental phases of maximal plasticity known as sensitive or critical periods. Neural correlates of sensory critical periods have been identified, but their roles remain unclear. Factors that define ... Read more...

Factors limiting song acquisition in adult zebra finches.

13 Sep 2009 Song learning takes place in two separate or partially overlapping periods, a sensory phase in which a tutor song is memorized and a sensorimotor phase in which a copy of the model is produced. The stage of song development where song becomes stable ... Read more...

Bilateral sequential cochlear implantation in the congenitally deaf child: evidence to support the concept of a 'critical age' after which the second ear is less likely to provide an adequate level of speech perception on its own.

30 Aug 2009 This study attempts to answer the question of whether there is a 'critical age' after which a second contralateral cochlear implant is less likely to provide enough speech perception to be of practical use. The study was not designed to predict ... Read more...
