Neural Algorithms of Human Language

Laura Gwilliams · Stanford University

…from population activity measured with MEG and intracranial EEG to individual neurons sampled across cortical depth with human Neuropixels probes. The studies ask which representations and operations connect speech sounds to meaning, and how information at different timescales is nested across time and cortical space. Comparing biological recordings with artificial models reveals candidate mechanisms for exchangin

…evidence that brain recordings (fMRI, MEG, ECoG) acquired while participants read or listened to unconstrained speech can be predicted by representations extracted from state-of-the-art text- and speech-based LLMs. In particular, text-based LLMs tend to align better with higher-level language regions, capturing more semantic aspects, while speech

Graph Signal Processing on MEG for Parkinson's disease

Valter Lundegårdh, Arvind Kumar, Pascal Helson · Bernstein Conference 2024

Brain activity lies on a very complex network. This complexity is multiple but a prominent one is the non-linear and multi-factorial interaction between its nodes. In the specific case of Parkinson's disease (PD), the brain loses dopaminergic neurons in the substantia nigra compacta (SNc). Highly involved in the basal ganglia-cortex-thalamus-cerebellum (BG-Ctx-T-Cb) network, the main role of dopamine (DA) is in learning, decision-making and motor control, as manifested in the PD symptoms such as rigidity, slowness of movements, tremor and poor behavioural flexibility. Following DA loss, the un

We compare several modern Bayesian inference schemes for model inversion on simulated data . We benchmark the identifiability of local parameters governing the interplay between several neuronal populations in each region, as well as global parameters t

Components of visual image and category information in human MEG

Jan Kevin Schlüsener, Malav Shah, Florian Sandhaeger et al. · FENS Forum 2024

Neural population signals recorded with magneto- (MEG) or electroencephalography (EEG) contain information about viewed natural images and their categories. However, it remains unclear which specific visual features contribute to this information. To address this, we applied spectral manipulations and different texturization algorithms to natural images of various categories and recorded MEG in human subjects presented with these stimuli. The employed stimulus space allowed us to attribute components of visual information to specific low-, mid- and high-level visual features. Furthermore, this

While EEG measurements have found a subcortically evoked early neural activity to this speech-FFR, MEG studies have recently emphasized involvement of cortical sources as well. Here, we focused on disentangling the sources of the neural response at the fundamental frequency of speech using EEG-based source localization. We theref

Social cognition refers to a range of processes that allow us to make sense of others' behaviors and engage in daily interactions. A key network supporting social cognition is the mirror neuron system (MNS), a set of fronto-parietal regions that allows inferring others' intentions through action observation. The MNS exhibits considerable plasticity based on an individual's motor repertoire, but little is known about its potential for reorganization in the presence of brain damage. To address this gap, we investigated the adaptive capacity of the MNS in patients with gliomas affecting key netwo

Movement planning as a window into hierarchical motor control

Katja Kornysheva · Centre for Human Brain (CHBH) at the University of Birmingham, UK

The ability to organise one's body for action without having to think about it is taken for granted, whether it is handwriting, typing on a smartphone or computer keyboard, tying a shoelace or playing the piano. When compromised, e.g. in stroke, neurodegenerative and developmental disorders, the individuals’ study, work and day-to-day living are impacted with high societal costs. Until recently, indirect methods such as invasive recordings in animal models, computer simulations, and behavioural markers during sequence execution have been used to study covert motor sequence planning in humans.

Navigating rodents show “forward sweeps” - sequential reactivation of non-local neural representations of future states starting from their current position. While direct evidence remains scant, it is widely thought that such forward sweeps support model-based (MB) evaluation of actions. However, a key challenge in testing this hypothesis is the absence of experimental paradigms that allow for precise measurement of MB action evaluation. Notably, typical assessments of MB evaluation, i.e. flexibility following changes to rewards (reward revaluation), conflate reliance on full MB evaluation wit

The dynamics of temporal attention

Rachel Denison · Boston University

Selection is the hallmark of attention: processing improves for attended items but is relatively impaired for unattended items. It is well known that visual spatial attention changes sensory signals and perception in this selective fashion. In the work I will present, we asked whether and how attentional selection happens across time. First, our experiments revealed that voluntary temporal attention (attention to specific points in time) is selective, resulting in perceptual tradeoffs across time. Second, we measured small eye movements called microsaccades and found that directing voluntary t

Electro- and magneto-encephalography (EEG/MEG) are the leading methods to non-invasively record human neural dynamics with millisecond temporal resolution. However, it can be extremely difficult to infer the underlying cellular and circuit level origins of these macro-scale signals without simultaneous invasive recordings. This limits the translation of E/MEG into novel principles of information processing, or into new treatment modalities for neural pathologies. To address this need, we developed the Human Neocortical Neurosolver (HNN: https://hnn.brown/edu ), a new user-friendly neural model

Autobiographical memories are the ghosts of our past. Through them we visit places long departed, see faces once familiar, and hear voices now silent. These, often decades-old, personal experiences can be recalled on a whim or come unbidden into our everyday consciousness. Autobiographical memories are crucial to cognition because they facilitate almost everything we do, endow us with a sense of self and underwrite our capacity for autonomy. They are often compromised by common neurological and psychiatric pathologies with devastating effects. Despite autobiographical memories being central t

Every day when we fall asleep we lose consciousness, we are not there. And then, every morning, when we wake up, we regain it. What mechanisms give rise to consciousness, and how can we explain consciousness in the realm of the physical world of atoms and matter? For centuries, philosophers and scientists have aimed to crack this mystery. Much progress has been made in the past decades to understand how consciousness is instantiated in the brain, yet critical questions remain: can we develop a consciousness meter? Are computers conscious? What about other animals and babies? We have embarked i
