Glioblastoma multiforme is the most common form of astrocytoma in adults. The incidence of these tumors is highest in the frontal lobes, followed by temporal and parietal lobes, basal ganglia, and occipital lobes. On computed tomography (CT) glioblastoma multiforme typically demonstrates characteristic findings of an irregular enhancing mass, usually surrounded by a significant amount of low-de...

Glossolalia (or "speaking in tongues") is an unusual mental state that has great personal and religious meaning. Glossolalia is experienced as a normal and expected behavior in religious prayer groups in which the individual appears to be speaking in an incomprehensible language. This is the first functional neuroimaging study to demonstrate changes in cerebral activity during glossolalia. The ...

Changes in cognition with aging have been claimed to be due in large part to a decline in frontal lobe function. However, at our present state of knowledge, the emphasis on the frontal lobes to the exclusion of the rest of the frontal-striatal circuits of which they are a part is unwarranted. To argue this point, I consider another anatomical candidate within these circuits, the caudate. Eviden...

Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder that can affect all age groups. It appears to have higher incidence in the female population. Some common risk factors include hypertension, electrolyte abnormalities, sepsis, and chemotherapeutic medications such as Obinutuzumab. Our patient, who had chronic lymphocytic leukemia (CLL), presented with altered mental ...

This article reviews and develops some theories about the neurobiological basis of creative innovation (CI). CI is defined as the ability to understand and express novel orderly relationships. A high level of general intelligence, domain-specific knowledge and special skills are necessary components of creativity. Specialized knowledge is stored in specific portions of the temporal and parietal...

The autism spectrum disorders (ASDs) are a complex group of neuropsychiatric conditions involving language, social communication, and mental flexibility. Here, we attempt to place recent genetic advances within a developmental and anatomical context. Recent progress in identifying ASD candidate genes supports involvement of multiple brain regions, including the frontal lobes, anterior temporal ...

We describe a 35-year-old man with a history of remote closed head injury who presented with new neurologic deficits. A noncontrast head CT scan showed hyperattenuation involving both temporal lobes, frontal lobes, basal meninges, and cerebellum. A subsequent contrast-enhanced MR examination of the brain showed enhancement in the basal cisterns extending into the upper cervical spine and throug...

We are reporting a female case of semantic dementia. Characteristic of this type of dementia, she could not recognize some objects such as a pencil, a ruler or her dominant hand. When shown a pencil, she would ask “What is a pencil?” Her brain MRI showed atrophy of bilateral temporal lobes, especially anterior poles. SPECT also showed abnormally decreased blood flow in temporal lobes and fronta...

Hypersexuality is a rare but well recognized condition following brain injury. It has been described secondarily to dysfunction in the hypothalamus, the temporal and frontal lobes. We report a 63 year-old man that developed neuropsychological disturbances with hypersexuality as a prominent feature, disinhibition and moderate memory loss, hypersomnia and irritability after a bilateral paramedian...

Patients with unilateral dorsolateral frontal lobe lesions and matched controls were given 2 tests of remote memory for public information, the Public Events Test and the Famous Faces Test. On both tests, the patients with frontal lobe lesions exhibited impaired recall for remote information. Recognition memory was relatively preserved. Provision of semantic and phonemic cues in the Famous Face...
