Understanding deep-layer brain nerve cells and how they are controlled
Multimodal analysis of primate infragranular pyramidal neurons and their modulation
This work looks at how specific deep-layer brain cells in humans and primates respond to ion channels and chemical signals, with implications for people with Alzheimer's and related brain disorders.

What this research studies
Researchers will study individual deep-layer (infragranular) neurons from human and nonhuman primate brain tissue to link each cell’s genes, shape, and electrical behavior. They will use Patch-seq, a method that records a cell’s electrical signals and captures its RNA so scientists can match function to gene expression. Viral labeling tools will help identify and follow particular neuron classes, especially layer 5 neurons that send signals to other brain regions. The team will test how specific ion channels and neuromodulator receptors change how these cells process input and produce output.
Who could benefit from this research
Good fit: People who donate brain tissue (for example through brain banks or certain neurosurgeries) or patients with Alzheimer’s or related conditions who participate in tissue donation programs would be the most relevant contributors.
Not a fit: Patients seeking immediate symptom relief or direct treatment are unlikely to benefit in the short term because this is laboratory-based, basic neuroscience research.
Why it matters
Potential benefit: If successful, this work could reveal which neuron types drive disease-related brain changes and point to new, more precise targets for Alzheimer’s treatments.
How similar studies have performed: Other single-cell and Patch-seq studies have successfully mapped neuron types and linked gene expression to cell properties, but direct translation into new therapies is still largely unproven.
