Why Are Sequence Representations in Primary Motor Cortex So Elusive?

Why Antagonistic Traits against Cytoplasmic Incompatibility Are So Elusive

Intracellular symbionts are present in a wide variety of animals, plants and other life forms (Correa and Ballard, 2016); and have an intriguing lifestyle. To enhance their spread, intracellular symbionts have evolved a variety of mechanisms. Some of them provide benefits to their host and are effectively mutualists (e.g., Buchnera in aphids; Douglas, 1998), while others bias the sex ratio of t...

Visuomotor representations within the human primary motor cortex: the elusive markers of visuomotor associative learning.

Muscle and movement representations in the primary motor cortex.

What aspects of movement are represented in the primary motor cortex (M1): relatively low-level parameters like muscle force, or more abstract parameters like handpath? To examine this issue, the activity of neurons in M1 was recorded in a monkey trained to perform a task that dissociates three major variables of wrist movement: muscle activity, direction of movement at the wrist joint, and dir...

Why are clicks so exclusive ?

Clicks occur abundantly in the languages of southern Africa, but are not found anywhere else. This is unexpected since the clicks seem to be both auditorily salient and easy to produce. This paper suggests that the reason for the areal skewness of clicks lies in the African phonetictypological environment rather than in production or perception constraints. In particular, clicks are limited to ...
