Figure 1
Stroke to the barrel cortex in mice unmasks existing latent functions but does not result in circuit reorganisation.
An illustration of whisker remapping in somatosensory barrel cortex post-stroke. (A) Distribution of whisker-responsive neurons in L4 (circles, via thalamic input) and L2/4 (triangles, via …

Artificial rewiring of retinal inputs into the ferret’s developing auditory thalamus.
(A) Top: Normally, retinal information is routed to the visual cortex directly via the lateral geniculate nucleus (LGN), as well as via the superior colliculus, whereas auditory information is …

Language is processed bilaterally.
(A) An example of a functional MRI (fMRI) activity map acquired during a language processing task (sentences versus nonwords contrast) in a typically developed individual. The prefrontal language …

Cortical ocular dominance in primary visual cortex is not categorical.
(A) Ocular dominance in the cats’ visual cortex, as originally reported by Hubel and Wiesel. In normally developed kittens, more cells show a preference to visual input from the contralateral eye …
Figure 5
The representational structure of natural object categories in ventral occipitotemporal cortex is invariant between sighted and blind participants.
The multivoxel representational structure across multiple natural object categories was studies in the visual domain in sighted controls, and compared with auditory representational structure found …

Cross-modal visual processing in higher-order auditory cortex has limited functional impact.
(A) Lateral view of the cat cortex highlighting the locations of the higher-order auditory areas posterior auditory field (PAF), dorsal zone (DZ), auditory field of the anterior ectosylvian sulcus …

Finger acuity in blind individuals doesn’t relate to map changes to somatosensory cortex.
(A) A replication of several classical studies showing that blind people (pink) exhibit on average better tactile acuity relative to sighted controls (grey), as measured using a tactile gratings …

Remapping in the primary somatosensory cortex (S1) hand map does not imply reorganisation.
(A) A finger map in the monkey’s S1, created using a winner-takes-all single-cell recording approach. The map shows clear boundaries between sub-regions dedicated to processing inputs for each of …

Face and hand representations can remain stable following arm deafferentation.
(A) The primary somatosensory (S1) hand area, shown from a lateral view (left) and through a cross-section of the central sulcus (middle). The colours along the postcentral bank of the sulcus …
Figure 10
Remapping of hand and arm representation following focal lesion doesn’t reflect motor recovery.
(A) Upper limb map in a monkey showing typical hand representation prior to M1 lesion (shown by white dashed line) and remapping of the hand representation after lesion to the digit area and …

Tool-use is not associated with increased embodiment.
(A) An example neuron from the famous study by Iriki and colleagues, showing spatially expanded ‘visual’ responses after the monkey used a tool (middle panel), relative to hand use (left) or passive …
