Lisa Giocomo

Definition
Lisa Giocomo is an American neuroscientist and academic researcher known for her contributions to the understanding of neuronal mechanisms underlying spatial navigation, particularly the function of grid cells in the entorhinal cortex.

Overview
Giocomo is a faculty member in the Department of Neuroscience at Johns Hopkins University School of Medicine, where she leads the Giocomo Laboratory. Her research focuses on how neuromodulatory signals and network dynamics generate and modulate spatial representations in the brain. The laboratory employs a combination of electrophysiology, two‑photon imaging, and computational modeling to investigate the cellular and circuit basis of grid cell activity and related spatial coding phenomena. Her work has advanced knowledge of how acetylcholine and other neuromodulators influence the stability and precision of grid cell firing patterns, with implications for memory, navigation, and neurological disorders.

Etymology/Origin
The surname “Giocomo” is of Italian origin, derived from the given name “Giocomo,” a variant of “Giacomo,” the Italian form of “James.” The given name “Lisa” is a diminutive of “Elisabeth,” originating from Hebrew meaning “God is my oath.”

Characteristics

• Academic Background – Giocomo earned a Ph.D. in Neurobiology (institution and year not publicly confirmed) and completed postdoctoral training focusing on cortical circuitry and spatial coding.
• Research Focus – Primary investigations center on:
  1. The electrophysiological properties of grid cells in the medial entorhinal cortex.
  2. The role of cholinergic and other neuromodulatory systems in modulating spatial maps.
  3. Computational models that link cellular mechanisms to large‑scale spatial representations.
• Key Publications – She has authored peer‑reviewed articles in journals such as Nature, Science, Neuron, and Cell Reports, addressing topics like “Grid cells and theta oscillations” and “Acetylcholine-dependent modulation of entorhinal spatial coding.”
• Awards and Honors – Giocomo has received recognition including the NIH Director’s New Innovator Award (2021) and fellowship support from organizations supporting early‑career neuroscientists.
• Professional Service – She serves on editorial boards for neuroscience journals and participates in scientific advisory panels related to brain research.

Related Topics

• Grid Cells – Neurons in the medial entorhinal cortex that fire at multiple locations forming a hexagonal lattice, essential for metric spatial navigation.
• Entorhinal Cortex – A cortical region that interfaces the hippocampus with neocortex, critical for memory and navigation.
• Spatial Navigation – Cognitive processes enabling organisms to determine and maintain position in an environment, often studied via place and grid cell systems.
• Neuromodulation – Chemical signaling (e.g., acetylcholine, dopamine) that alters neuronal excitability and synaptic plasticity, influencing spatial coding.
• Computational Neuroscience – The discipline that uses mathematical models to understand neural system function, a methodological component of Giocomo’s work.
