Visual Aftereffects: Cortical Neurons Change Their Tune

Recent studies of areas V1 and MT in the visual cortex show that exposure to a stimulus can change the contrast sensitivity of cells and shift their peak sensitivity to a new orientation or movement direction. In MT, these shifts can correctly predict illusory changes - visual aftereffects - in movement direction, but in V1, they are more difficult to interpret.

Will paying the piper change the tune?

Most provincial governments are considering or introducing changes to hospital funding. Ten years of rapidly increasing expenditures have left them still facing complaints of waiting lists and waiting times.

To make this argument we draw on two discrete sets of data: a review of leadership compet...

Musicians change their tune: how hearing loss alters the neural code.

Individuals with sensorineural hearing loss have difficulty understanding speech, especially in background noise. This deficit remains even when audibility is restored through amplification, suggesting that mechanisms beyond a reduction in peripheral sensitivity contribute to the perceptual difficulties associated with hearing loss. Given that normal-hearing musicians have enhanced auditory per...

Birdsong: Can an old bird change his tune?

The song of a male songbird is the polished product of a vocal learning process which, like human speech, happens early in life, occurs in stages and requires auditory guidance. One apparent difference between birdsong and speech is that the adult song of certain songbird species is unaltered by deafening whereas, without hearing, speech degrades. Birdsong and human speech may be more alike tha...
