[PDF][PDF] Neural manifolds for the control of movement

JA Gallego, MG Perich, LE Miller, SA Solla - Neuron, 2017 - cell.com
The analysis of neural dynamics in several brain cortices has consistently uncovered low-dimensional
manifolds that capture a significant fraction of neural variability. These neural …

Rethinking brain-wide interactions through multi-region 'network of networks' models

MG Perich, K Rajan - Current opinion in neurobiology, 2020 - Elsevier
Highlights • Brains can be viewed as a composition of anatomically distinct modules called
regions. • Brain regions interact in complex ways to form a ‘network of networks’. • Untangling …

Long-term stability of cortical population dynamics underlying consistent behavior

JA Gallego, MG Perich, RH Chowdhury, SA Solla… - Nature …, 2020 - nature.com
Animals readily execute learned behaviors in a consistent manner over long periods of time,
and yet no equally stable neural correlate has been demonstrated. How does the cortex …

[HTML][HTML] Cortical population activity within a preserved neural manifold underlies multiple motor behaviors

JA Gallego, MG Perich, SN Naufel, C Ethier… - Nature …, 2018 - nature.com
Populations of cortical neurons flexibly perform different functions; for the primary motor
cortex (M1) this means a rich repertoire of motor behaviors. We investigate the flexibility of M1 …

Machine learning for neural decoding

JI Glaser, AS Benjamin, RH Chowdhury, MG Perich… - Eneuro, 2020 - eneuro.org
Despite rapid advances in machine learning tools, the majority of neural decoding approaches
still use traditional methods. Modern machine learning tools, which are versatile and …

A spinal cord neuroprosthesis for locomotor deficits due to Parkinson's disease

…, C Moerman, F Raschellà, S Sun, MG Perich… - Nature Medicine, 2023 - nature.com
People with late-stage Parkinson’s disease (PD) often suffer from debilitating locomotor
deficits that are resistant to currently available therapies. To alleviate these deficits, we …

[PDF][PDF] A neural population mechanism for rapid learning

MG Perich, JA Gallego, LE Miller - Neuron, 2018 - cell.com
Long-term learning of language, mathematics, and motor skills likely requires cortical
plasticity, but behavior often requires much faster changes, sometimes even after single errors. …

[HTML][HTML] Preserved neural dynamics across animals performing similar behaviour

…, JC Chang, J Park, LE Miller, JT Dudman, MG Perich… - Nature, 2023 - nature.com
Animals of the same species exhibit similar behaviours that are advantageously adapted to
their body and environment. These behaviours are shaped at the species level by selection …

Epidural electrical stimulation of the cervical dorsal roots restores voluntary upper limb control in paralyzed monkeys

B Barra, S Conti, MG Perich, K Zhuang… - Nature …, 2022 - nature.com
… once per day for 5 d (Rimadyl 4 mg kg −1 , subcutaneous (sc); dexamethasone 0.3 mg kg
−1 , sc) and analgesic was given twice per day for 5 d (Temgesic 0.01 mg kg −1 , im). Within …

Rapid adaptation of brain–computer interfaces to new neuronal ensembles or participants via generative modelling

S Wen, A Yin, T Furlanello, MG Perich… - Nature Biomedical …, 2023 - nature.com
For brain–computer interfaces (BCIs), obtaining sufficient training data for algorithms that map
neural signals onto actions can be difficult, expensive or even impossible. Here we report …
