1. Alice in Wonderland syndrome: “Who in the world am I?”
RESUMO Síndrome de Alice no País das Maravilhas (SAPM) é uma condição paroxística visual perceptiva e somestésica que pode ser encontrada em pacientes com enxaqueca, epilepsia, doença cerebrovascular ou infecções. A condição é relativamente rara e tem características alucinatórias peculiares. Objetivo: Discutir as potenciais vias envolvidas n

2. From anatomy to function: the role of the somatosensory cortex in emotional regulation
Since the pioneering work of Penfield and his colleagues in the 1930s, the somatosensory cortex, which is located on the postcentral gyrus, has been known for its central role in processing sensory information from various parts of the body. More recently, a converging body of literature has shown that the somatosensory cortex also plays an important role

3. Morphometric analysis of feedforward pathways from the primary somatosensory area (S1) of rats
We used biotinylated dextran amine (BDA) to anterogradely label individual axons projecting from primary somatosensory cortex (S1) to four different cortical areas in rats. A major goal was to determine whether axon terminals in these target areas shared morphometric similarities based on the shape of individual terminal arbors and the density of two bouton

4. Early sensory re-education of the hand after peripheral nerve repair based on mirror therapy: a randomized controlled trial
BACKGROUND: Mirror therapy has been used as an alternative stimulus to feed the somatosensory cortex in an attempt to preserve hand cortical representation with better functional results. OBJECTIVE: To analyze the short-term functional outcome of an early re-education program using mirror therapy compared to a late classic sensory program for hand nerve

5. Efeitos da estimulação transcraniana por corrente contínua em tarefas de percepção tátil manual - desempenho tátil entre indivíduos com visão preservada e deficientes visuais
A integridade do sistema sensorial é importante para o desenvolvimento das habilidades humanas. Entretanto, com a perda de um ou mais sentidos, a capacidade do sistema nervoso em adaptar-se a nova condição é variável devido ao tipo e idade de perda e outros fatores envolvidos na aprendizagem de novas habilidades, como na plasticidade neural. Todavia, es

6. "Computational simulations biologically plausible of neurons of the primary somatosensory cortex" / "Simulações computacionais biologicamente plausíveis de neurônios do córtex somestésico primário"
Since its appearance, the computer has been used to model phenomena in all areas of knowledge. In neuroscience, computer modeling is used to describe, reproduce and predict behaviors of different components of the nervous system. As well as in other areas of sciences, this procedure has been shown to be efficient in the study and improvement of theories on b

7. Potencial evocado somotossensorial por estimulação do nervo mediano nas lesões Vasculares cerebrais hemisfericas : estudos dos potenciais de media latencia em relação a lesões cerebrais documentadas por ressonancia magnetica do cranio e ao potencial N20
Middle latency somatosensory evoked potentials were recorded by electrical stimulation of the median nerve at the wrist, in 43 patients with hemispheric cerebrovascular lesions. Forty two patients were examined within the third and fourth weeks, and in one case, in the fourth month afier a stroke. Ali the lesions were documented by Magnetic Resonance Imaging

8. Callosal projections in rat somatosensory cortex are altered by early removal of afferent input.
During the first postnatal week, the distribution of callosal projection neurons in the rat somatosensory cortex changes from a uniform to a discontinuous pattern. To determine if this change is influenced by afferent inputs to the somatosensory cortex, the effect of both early unilateral infraorbital nerve section and unilateral removal of the dorsal thalam

9. Somatosensory cortex dominated by the representation of teeth in the naked mole-rat brain
We investigated naked mole-rat somatosensory cortex to determine how brain areas are modified in mammals with unusual and extreme sensory specializations. Naked mole-rats (Heterocephalus glaber) have numerous anatomical specializations for a subterranean existence, including rows of sensory hairs along the body and tail, reduced eyes, and ears sensitive to l

10. Visual responses of neurons in somatosensory cortex of hamsters with experimentally induced retinal projections to somatosensory thalamus.
These experiments investigate the capacity of thalamic and cortical structures in a sensory system to process information of a modality normally associated with another system. Retinal ganglion cells in newborn Syrian hamsters were made to project permanently to the main thalamic somatosensory (ventrobasal) nucleus. When the animals were adults, single unit

11. Cholinergic depletion prevents expansion of topographic maps in somatosensory cortex.
Although the role of acetylcholine in processing stimuli in the cerebral cortex is becoming defined, the impact of cholinergic activity on the character of cortical maps remains unclear. In the somatosensory cortex, topographic maps appear capable of lifelong modifications in response to alterations in the periphery. One factor proposed to influence this ada

12. Beta 2-adrenergic receptors are colocalized and coregulated with "whisker barrels" in rat somatosensory cortex.
Autoradiography has been used to visualize independently the subtypes of beta-adrenergic receptors in rat somatosensory cortex. Beta 2-Adrenergic receptors, but not beta 1-adrenergic receptors colocalize with "whisker barrels" in this tissue. Thus, each whisker sends a specific multisynaptic pathway to the somatosensory cortex that can be histochemically vis
