Mars – BrainStrucFunc – The extreme capsule fiber complex in humans and macaque monkeys: a comparative diffusion MRI tractography study

We compared the course and cortical projec- tions of white matter fibers passing through the extreme capsule in humans and macaques. Previous comparisons of this tract have suggested a uniquely human posterior pro- jection, but these studies have always employed different techniques in the different species. Here we used the same technique, diffusion MRI, in […]

Johnen – eLife – Causal manipulation of functional connectivity in a specific neural pathway during behaviour and at rest

Correlations in brain activity between two areas (functional connectivity) have been shown to relate to their underlying structural connections. We examine the possibility that functional connectivity also reflects short-term changes in synaptic efficacy. We demonstrate that paired transcranial magnetic stimulation (TMS) near ventral premotor cortex (PMv) and primary motor cortex (M1) with a short 8-ms […]

Stolk – PNAS – Cerebral coherence between communicators marks the emergence of meaning

How can we understand each other during communicative inter- actions? An influential suggestion holds that communicators are primed by each other’s behaviors, with associative mechanisms au- tomatically coordinating the production of communicative signals and the comprehension of their meanings. An alternative sugges- tion posits that mutual understanding requires shared conceptuali- zations of a signal’s use, […]

Mars – FrontNeurosci – Primate comparative neuroscience using magnetic resonance imaging: promises and challenges

Primate comparative anatomy is an established field that has made rich and substantial contributions to neuroscience. However, the labor-intensive techniques employed mean that most comparisons are often based on a small number of species, which limits the conclusions that can be drawn. In this review we explore how new developments in magnetic resonance imaging have […]

Verhagen – thesis – How to grasp a ripe tomato

How to grasp a ripe tomato? Fortunately, we don’t have to think about this when we are standing in the supermarket after a busy day. We carefully grasp that ripe tomato without effort. Such a fluent integration of abstract knowledge (“that tomato is ripe”) and spatial information (“it is there”) is actually extraordinary. While modern […]

Volman – CerebCortex – Endogenous testosterone modulates prefrontal–amygdala connectivity during social emotional behavior

It is clear that the steroid hormone testosterone plays an important role in the regulation of social emotional behavior, but it remains unknown which neural circuits mediate these hormonal influences in humans. We investigated the modulatory effects of endogenous testosterone on the control of social emotional behavior by applying functional magnetic resonance imaging while healthy […]

Verhagen – JNeurosci – Perceptuo-motor interaction during prehension movements

Adaptive behavior relies on the integration of perceptual and motor processes. In this study, we aimed at characterizing the cerebral processes underlying perceptuo-motor interactions evoked during prehension movements in healthy humans, as measured by means of functional magnetic resonance imaging. We manipulated the viewing conditions (binocular or monocular) during planning of a prehen- sion movement, […]

Grol – JNeurosci – Parieto-frontal connectivity during visually guided grasping

Grasping an object requires processing visuospatial information about the extrinsic features (spatial location) and intrinsic features (size, shape, orientation) of the object. Accordingly, manual prehension has been subdivided into a reach component, guiding the hand toward the object on the basis of its extrinsic features, and a grasp component, preshaping the fingers around the center […]

Majdandzic – NeuroImg – The role of immediate and final goals in action planning: an fMRI study

To interact effectively with our environment, we need to specify the intended outcomes (goals) of our actions. In this process, immediate goals and final goals can be regarded as different levels within a hierarchically organized system for action planning: immediate goals and movement details are selected to accomplish more remote goals. Behavioral studies support this […]
