Neural Plasticity

A requirement of learning and memory is a brain capable of stably encoding change. Throughout our lives, in response to our experiences, our neurons form new synaptic connections and prune away others. Scientists in the Picower Institute study these processes of plasticity, elucidating their workings down to the molecule, to better understand how they work.

Synapse Mapping

A typical neuron has thousands of synapses that connect it with other neurons in neural circuits. The location, type and constantly changing strength of each of these synapses determine how each neuron plays its role in the brain and how circuits are remodeled by experience. Research at the Picower Institute to map synapses is therefore essential to understanding how neural connections underlie brain functions and disease.

Genetic Engineering

Biological research often calls for imbuing cells, tissue, or animal models in the lab with specific new capabilities – or disabilities, for instance to observe the differences between altered and unaltered cells. Picower Institute neuroscientists employ advanced techniques such as CRISPR/Cas9, 3D stem cell and printing technologies, and transgenics to conduct such experiments.

Alzheimer's disease

Alzheimer’s disease and other dementias are neurodegenerative conditions characterized by a progressive loss of some mental functions, such as memory loss and cognitive decline. Through fundamental research on how the brain stores and recalls memory and on the biology of neurodegeneration, Picower researchers are developing crucial insights and working to translate them into potential therapies.
