    The Brown Lab is focused on the function of the cerebral cortex in the brain, which underlies our ability to interact with our environment through sensory perception and voluntary movement. Our research takes a bottom-up approach to understanding how the circuits of this massively interconnected network of neurons are functionally organized, and how dysfunction in these circuits contributes to neurodegenerative diseases like amyotrophic lateral sclerosis and neuropsychiatric disorders, including autism and schizophrenia. By combining electrophysiological and optogenetic approaches with anatomical and genetic techniques for identifying cell populations and pathways, the Brown Lab is defining the synaptic interactions among different classes of cortical neurons and determining how long-range and local inputs are integrated within cortical circuits. In amyotrophic lateral sclerosis, corticospinal and spinal motor neurons progressively degenerate. The Brown Lab is examining how abnormal activity within cortical circuits contributes to the selective degeneration of corticospinal motor neurons in an effort to identify new mechanisms for treating this disease. Abnormalities in the organization of cortical circuits and synapses have been identified in genetic and anatomical studies of neuropsychiatric disease. We are interested in the impact these abnormalities have on cortical processing and their contribution to the disordered cognition typical of autism and schizophrenia.

    Our laboratory is interested in understanding the neural basis of auditory perception and vocal communication in a naturalistic environment. We are interested in revealing neural coding mechanisms operating in the cerebral cortex and how cortical representations of biologically important sounds emerge through development and learning.
