Labs

 Rodrigo Braga Lab

Investigating the relationship between neural activity within brain-networks and cognitive functions

Research Description

The Braga Lab is investigating the relationship between neural activity within large-scale brain networks and cognitive functions that are advanced in humans, such as the use of language or thinking about the past or future. These functions are localized to associative regions of the brain that have disproportionately expanded in recent hominin evolution and are separated from information processing hierarchies devoted to any single sensory modality. By mapping brain networks in association areas with precision within individual volunteers using functional MRI, and measuring neural population activity using intracranial techniques, we can characterize brain networks at high spatial and temporal resolution and make insights into their specialization and function. A major focus of the lab is to study the nature of cross-network interactions and the role these play in different cognitive processes.

Genetic causes and pathogenic mechanism that underlie epilepsy

Research Description

The primary goal of our research is to use gene discovery and molecular biology approaches to identify new treatments for epilepsy. We aim to 1) identify the genetic causes of epilepsy, 2) use stem cell models to understand how genetic mutations can cause epilepsy, 3) develop and test new therapeutics for this condition. Our work is based on the promise of precision medicine where knowledge of an individual’s genetic makeup shapes a personalized approach to care and management of epilepsy.

Current Projects

  • Next generation sequencing in patients with epilepsy
  • Alternative exon usage during neuronal development
  • Identify the regulatory elements that control expression of known epilepsy genes
  • Stem cell genetic models for studying the epigenetic basis of epilepsy

Investigating ways to assist people with neurologic disorders through brain-machine interfaces.

Research Description

The goal of our research is to help people with neurologic disorders, especially those who are severely paralyzed from stroke, spinal cord injury, cerebral palsy, or ALS. Our research centers around using neural prosthetics, i.e., human machine interfaces, to help restore or replace function of the injured nervous system. We study brain-machine interfaces in monkeys and humans, allowing them to control a computer cursor or virtual hand directly from their brain signals. These signals are obtained via electrodes implanted in or on the surface of the brain or dura mater. In addition, we are investigating the potential to decode a person’s intended speech directly from his or her brain and using this to restore communication to people who have lost it due to severe paralysis. We also use this powerful paradigm to study the underlying relationship between different types of brain signals, for example, the relationship between field potentials (summed from many neurons in the network) and action potentials of individual neurons. Finally, we are developing a myoelectric computer interface to help survivors of stroke regain function in their arms.

We use fMRI, EEG and invasive EEG methods to study neural oscillations in the human olfactory system, their link to the respiratory cycle, and their propagation to downstream limbic areas involved in emotion and memory processing.

Research Description

The respiratory rhythm is inherently linked to olfaction; it is not possible to encounter an odor without first inhaling through the nose. Thus respiration imposes a natural rhythm of stimulus sampling in the olfactory system. In the mammalian olfactory bulb, local field potentials oscillate in phase with breathing, regulating cortical excitability, synchronizing activity within cell assemblies and coordinating network interactions, thus shaping olfactory sensory coding, memory and behavior. Due to timing constraints with neuroimaging techniques such as functional magnetic resonance imaging (fMRI), and anatomical constraints with surface EEG recordings, very little is known about respiratory oscillations in the human olfactory system. We use invasive EEG methods (iEEG) to examine how the respiratory rhythm is represented in the human olfactory system, and how this representation changes during different attentional states, and in the presence of odor. We are also interested in the propagation of respiratory oscillations from olfactory cortex to other nearby limbic areas such as the amygdala and the hippocampus, and how these limbic respiratory-linked oscillations impact cognitive functions. We are currently developing fMRI and surface EEG protocols for studying human respiratory oscillations originating in olfactory brain regions that don’t require iEEG methods.

Another goal of the lab is to understand the neural correlates of olfactory attentional mechanisms. The olfactory system is anatomically unique in that it has no pre-cortical thalamic relay. Rather, the olfactory system has a very small contingent of fibers projecting to the mediodorsal thalamic downstream from primary olfactory cortex. While this small contingent likely plays a role in olfactory attention, the unique anatomical organization of the olfactory thalamic relay suggests that olfactory attentional mechanisms may differ from other modalities. We use psychophysics, fMRI and iEEG methods to examine attentional mechanisms such as selective attention and predictive coding within the olfactory system.
