This technique allows the detailed analysis of putative local synaptic inputs to the neuron of interest. Medicine Making Sense of Listening: The IMAP Test Battery Johanna G. Barry*1, Melanie A. Ferguson*2, David R. Moore*1 1MRC Institute of Hearing Research, 2NIHR, National Biomedical Research Unit in Hearing A test battery (IMAP) for performing an in-depth assessment of auditory and cognitive abilities contributing to listening skills is described. It is quick to administer, child-friendly and free from linguistic confounds. Stimulus generation and protocol management are controlled via a software platform (IHR-STAR) to ensure replicable procedures.
