Human Circuits

How do cells, synapses, and circuits give rise to computations in our own human brain?

Who, what, where

The brain is the most complex processor we know of, built from a diverse array of cells, communicating through complex signalling.

We are a new research team at Hospital del Mar Research Institute (HMRIB), using the unique opportunity offered by surgical patient samples to understand how human circuits are arranged to process information. Through close research-clinic collaboration, we apply cutting-edge electrophysiology and super-resolution imaging approaches to explore cell and synapse function in humans, ultimately aiming to understand how human brain computations arise, and are specifically altered in disease.

News & Updates

Aug 2026 Two populations of CA3 neurons, one shown in blue and white, the other in orange
Preprint highlighted by The Transmitter

Our recent preprint demonstrates that hippocampal CA3 comprises two molecularly distinct cell types, with distinct functional and connective properties, challenging the model of CA3 as one uniform network. This work was highlighted by The Transmitter.

July 2025 CA3 neurons recorded from a slice of human hippocampal tissue
Findings covered by ThePrint

Our insights into circuit arrangement in human CA3 were the basis of ThePrint's feature "Are we just mice with culture?"
