Change in pattern of ongoing cortical activity with auditory category learning

FW Ohl, H Scheich, WJ Freeman - Nature, 2001 - nature.com
Humans are able to classify novel items correctly by category 1 , 2 ; some other animals
have also been shown to do this 3 , 4 , 5 , 6 , 7 . During category learning, humans group …

Learning-induced plasticity in animal and human auditory cortex

FW Ohl, H Scheich - Current opinion in neurobiology, 2005 - Elsevier
Recent data on learning-related changes in animal and human auditory cortex indicate functions
beyond mere stimulus representation and simple recognition memory for stimuli. Rather…

Enhanced cognitive flexibility in reversal learning induced by removal of the extracellular matrix in auditory cortex

…, LL Castiblanco Rivera, FW Ohl… - Proceedings of the …, 2014 - National Acad Sciences
During brain maturation, the occurrence of the extracellular matrix (ECM) terminates juvenile
plasticity by mediating structural stability. Interestingly, enzymatic removal of the ECM …

Bilateral ablation of auditory cortex in Mongolian gerbil affects discrimination of frequency modulated tones but not of pure tones

FW Ohl, W Wetzel, T Wagner, A Rech… - Learning & …, 1999 - learnmem.cshlp.org
This study examines the role of auditory cortex in the Mongolian gerbil in differential conditioning
to pure tones and to linearly frequency-modulated (FM) tones by analyzing the effects …

Spectral integration in primary auditory cortex attributable to temporally precise convergence of thalamocortical and intracortical input

MFK Happel, M Jeschke, FW Ohl - Journal of Neuroscience, 2010 - Soc Neuroscience
Primary sensory cortex integrates sensory information from afferent feedforward thalamocortical
projection systems and convergent intracortical microcircuits. Both input systems have …

Non-sensory cortical and subcortical connections of the primary auditory cortex in Mongolian gerbils: bottom-up and top-down processing of neuronal information via …

E Budinger, A Laszcz, H Lison, H Scheich, FW Ohl - Brain research, 2008 - Elsevier
In the present study, we will provide further anatomical evidence that the primary auditory
cortex (field AI) is not only involved in sensory processing of its own modality, but also in …

Orderly cortical representation of vowels based on formant interaction

FW Ohl, H Scheich - … of the National Academy of Sciences, 1997 - National Acad Sciences
Psychophysical experiments have shown that the discrimination of human vowels chiefly
relies on the frequency relationship of the first two peaks F1 and F2 of the vowel’s spectral …

Differential neuromodulation of acquisition and retrieval of avoidance learning by the lateral habenula and ventral tegmental area

…, A Ilango, H Scheich, W Wetzel, FW Ohl - Journal of …, 2010 - Soc Neuroscience
Several studies suggest an opponent functional relationship between the lateral habenula (LHb)
and the ventral tegmental area (VTA). Previous work has linked LHb activation to the …

Differential frequency conditioning enhances spectral contrast sensitivity of units in auditory cortex (field Al) of the alert Mongolian gerbil

FW Ohl, H Scheich - European Journal of Neuroscience, 1996 - Wiley Online Library
Differential aversive auditory conditioning in the awake Mongolian gerbil was performed during
single‐ and multi‐unit recording in field Al of the primary auditory cortex. Presentations of …

Global versus local processing of frequency-modulated tones in gerbils: an animal model of lateralized auditory cortex functions

W Wetzel, FW Ohl, H Scheich - Proceedings of the National …, 2008 - National Acad Sciences
Hemispheric asymmetries of speech and music processing might arise from more basic
specializations of left and right auditory cortex (AC). It is not clear, however, whether such …
