Ultra-high density electrodes improve detection, yield, and cell type identification in neuronal recordings

Kavli Affiliate: Xiaoqin Wang | Authors: Liam Paninski and Nathaniel Sawtell | Summary: To understand the neural basis of behavior, it is essential to sensitively and accurately measure neural activity at single neuron and single spike resolution. Extracellular electrophysiology delivers this, but it has biases in the neurons it detects and it imperfectly resolves their […]

Tonotopic organization of auditory cortex in awake marmosets revealed by multi-modal wide-field optical imaging

Kavli Affiliate: Xiaoqin Wang | Authors: Xindong Song, Yueqi Guo, Chenggang Chen, Jong Hoon Lee and Xiaoqin Wang | Summary: Tonotopic organization of the auditory cortex has been extensively studied in many mammalian species using various methodologies and physiological preparations. Tonotopy mapping in primates, however, is more limited due to constraints such as cortical folding, […]

Activation of hypoactive parvalbumin-positive fast-spiking interneuron restores dentate inhibition to prevent epileptiform activity in the mouse intrahippocampal kainate model of temporal lobe epilepsy

Kavli Affiliate: Jin Kang | Authors: Sang-Hun Lee, Young-Jin Kang and Bret N Smith | Summary: Parvalbumin-positive (PV+) GABAergic interneurons in the dentate gyrus provide powerful perisomatic inhibition of dentate granule cells (DGCs) to prevent overexcitation and maintain the stability of dentate gyrus circuits. Most dentate PV+ interneurons survive status epilepticus, but surviving PV+ interneuron […]

Three-dimensional reconstruction of fetal rhesus macaque kidneys at single-cell resolution reveals complex inter-relation of structures

Kavli Affiliate: Denis Wirtz | Authors: Lucie Dequiedt, Andre Forjaz, Jamie O. Lo, Owen J McCarty, Pei-Hsun Wu, Avi Rosenberg, Denis Wirtz and Ashley L. Kiemen | Summary: Kidneys are among the most structurally complex organs in the body. Their architecture is critical to ensure proper function and is often impacted by diseases such as […]

A mathematical theory of relational generalization in transitive inference

Kavli Affiliate: Vincent Ferrera | Authors: Samuel Lippl, Kenneth Kay, Greg Jensen, Vincent P. Ferrera and L.F. Abbott | Summary: Humans and animals routinely infer relations between different items or events and generalize these relations to novel combinations of items (“compositional generalization”). This allows them to respond appropriately to radically novel circumstances and is fundamental […]

Foraging Under Uncertainty Follows the Marginal Value Theorem with Bayesian Updating of Environment Representations

Kavli Affiliate: Daeyeol Lee | Authors: James Webb, Paul Steffan, Benjamin Y Hayden, Daeyeol Lee, Caleb Kemere and Matthew McGinley | Summary: Foraging theory has been a remarkably successful approach to understanding the behavior of animals in many contexts. In patch-based foraging contexts, the marginal value theorem (MVT) shows that the optimal strategy is to […]

Learning enhances behaviorally relevant representations in apical dendrites

Kavli Affiliate: Elizabeth Hillman | Authors: Sam E. Benezra, Kripa B. Patel, Citlali Pérez Campos, Elizabeth M. C. Hillman and Randy M Bruno | Summary: Learning alters cortical representations and improves perception. Apical tuft dendrites in Layer 1, which are unique in their connectivity and biophysical properties, may be a key site of learning-induced plasticity. […]

Contributions of mirror-image hair cell orientation to mouse otolith organ and zebrafish neuromast function

Kavli Affiliate: Kathleen Cullen | Authors: Kazuya Ono, Amandine Jarysta, Natasha Hughes, Alma Jukic, Vanessa H.H. Chang, Michael R Deans, Ruth Anne Eatock, Kathleen E Cullen, Katie S Kindt and Basile Tarchini | Summary: Otolith organs in the inner ear and neuromasts in the fish lateral-line harbor two populations of hair cells oriented to detect […]
