Description of the dataset

Description: Data includes electrophysiological recordings (EEG, electroencephalography) of anesthetised rats (two groups, n = 10 each) and of human adults (n = 20). The human participants were passively exposed to foreign language speech sounds between pre- and post measurements. The each groups of rats were exposed for three nights to different speech sound features (either to phoneme durations or spectrotemporal changes), and responses for both features were measured.

Data has been used to investigate the contribution of the different levels of the auditory pathway in auditory perceptual learning and the effects of the short-term passive exposure to speech sounds in human and rodent brain. The lower levels of the auditory pathway, i.e. the thalamus and inferior colliculus, are interconnected with auditory cortex via many afferent and efferent neural pathways. It is unknown, however, whether the subcortical plasticity, demonstrated previously in single cell recordings, occurs without feedback from the auditory cortex. To investigate this, plastic changes along the auditory pathway will be measured with local field potentials and single cell recordings in rats and electroencephalography (EEG) in humans to speech sounds in similar stimulus conditions.
