We report a case of an adult man who was run over by a car, suffering severe head trauma. After 3 hours in the hospital, he experienced sudden and severe hemodynamic deterioration, dying immediately. The autopsy showed massive cerebral tissue pulmonary embolization
(CTPE), confirmed by immunohistochemistry. Multiple fractures of the skull, tear of the transverse sinus, and brain laceration of the occipital lobe were present.
Synchronous spiking of neural populations is hypothesized to play important computational roles in forming neural assemblies and solving the binding problem. Although the opposite phenomenon of desynchronization is well known from EEG studies, it is largely neglected on the neuronal level.
We tested the involvement of cognition in adult experience-dependent neuroplasticity using primate cortical implants. In a prior study, learning an operant sensory discrimination increased cortical excitability and target selectivity.
The ability to associate some stimuli while differentiating between others is an essential characteristic of biological memory. Theoretical models identify memories as attractors of neural network activity, with learning based on
Hebb-like synaptic modifications.

Severe head injury (SHI) is one of the most important health, social and economic problems in industrialised countries. Unfortunately, none of the neuroprotection trials for traumatic brain injury have shown efficacy. One of the reasons for this failure could be the inclusion of patients with high probability of early death. A population-based, retrospective study was conducted to develop a prognostic model for identification of these patients.
Peter Kan, M.D., et al. - Conclusion: Posttraumatic hydrocephalus and epilepsy were common complications encountered by children with severe TBI who underwent decompressive
craniectomy. In patients who underwent decompressive surgery for raised ICP only, the mortality rate was exceedingly high.

Different methods are often used to deter head injury patients, who have a tendency to wander, from leaving the rehabilitation wards. The extent to which these patients could be restrained is controversial. Despite the fact that the majority of these patients lack mental capacity, Mental Health Act sections are rarely invoked. Under common law, informal patients should have the right to refuse treatment and to leave the hospital whenever they like.
Disability & Rehabilitation Volume 28, Number 22 / November 2006 1379 - 1386

The two most common types of acquired reading disorder resulting from damage to the territory of the dominant posterior cerebral artery are hemianopic and pure alexia. Patients with pronounced hemianopic alexia have a right homonymous hemianopia that encroaches into central or parafoveal vision; they read individual words well, but generate inefficient reading saccades when reading along a line of text. Patients with pure alexia also often have a hemianopia but are more disabled, making frequent errors on individual words; they have sustained damage to a brain region that supports efficient word identification.
Intracranial hydatidosis is mainly a pediatric disease. Surgical evacuation of the mass in toto is the gold standard of therapy. No concise data related to the requirement of diversion procedures after uncomplicated hydatid cyst removal is encountered in the literature.
Paediatric neuroradiology has become highly specialised over the past 30 years. The power and versatility of the different imaging modalities has grown rapidly over this period, alongside a greater understanding of their limitations.
