Medical Research Council Institute of Hearing Research, University of Nottingham, Nottingham NG7 2RD, United Kingdom
J Neurophysiol 84:844-52. 2000..6 dB (NoSo vs. NpiSo) compared with 6.6 dB for the NoSo versus NoSpi BMLD we had previously reported. This lower magnitude is consistent with the hierarchy of human psychophysical BMLDs...
- GABAergic inhibition controls neural gain in inferior colliculus neurons sensitive to interaural time differencesNeil J Ingham
The Ear Institute and Department of Physiology, University College London, London WC1E 6BT, United Kingdom
J Neurosci 25:6187-98. 2005..This gain control appears to arise from a combination of additive and multiplicative processes, and may involve mechanisms such as shunting inhibition or changes in the efficacy of inhibitory and excitatory inputs...

Department of Physiology, University College London, Gower Street, London, WC1E 6BT, United Kingdom
J Neurophysiol 91:632-45. 2004..We conclude that such binaurally derived measures of adaptation reflect processes that occur above the level of exclusively monaural pathways, and subsequent to the site of primary binaural interaction...
