Discusses neocortical contributions to emotional processing. Examines parameters critical to neuropsychological study of emotion: interhemispheric and intrahemispheric factors, processing mode, and communication channel. Describes neuropsychological theories of emotion. Reviews studies of right-brain-damaged, left-brain-damaged, and normal adults,…

Auditory evoked responses (AER) of 14 infants were recorded by means of scalp electrodes positioned over frontal, temporal, and parietal regions of each hemisphere before and after training in which nonsense bisyllables were used to name novel objects. Changes in two portions of AER waveforms were found to occur when a name was correctly paired…

The retrieval of temporal-order versus spatial-location information was investigated using fMRI. The primary finding in the hippocampus proper, seen in region of interest analyses, was an increase in BOLD signal intensity for temporal retrieval, and a decrease in signal intensity for spatial retrieval, relative to baseline. The negative BOLD…

This study investigates whether the right hemisphere has more flexible contrast gain control settings for the identification of spatial frequency. Right-handed participants identified 1 and 9 cycles per degree sinusoidal gratings presented either to the left visual field-right hemisphere (LVF-RH) or the right visual field-left hemisphere (RVF-LH).…

Recent developments in neuroscience provide important information for therapists working with maltreated children. Severe maltreatment and lack of significant attachment figures in the crucial early years lead to adverse brain development (De Bellis, 2001). It appears evident that traumatic memories are stored in the right hemisphere, making…

The cerebral hemispheres have been proposed to engage different word recognition strategies: the left hemisphere implementing a parallel, and the right hemisphere, a sequential, analysis. To investigate this notion, we asked participants to name words with an early or late orthographic uniqueness point (OUP), presented horizontally to their left…

This paper discusses the current fashion for brain-based learning, in which value-laden claims about learning are grounded in neurophysiology. It argues that brain science cannot have the authority about learning that some seek to give it. It goes on to discuss whether the claim that brain science is relevant to learning involves a category…

Howard Garner's book Multiple Intelligences was important in psychology because it sought to relate a neuropsychological theory of common mental processes with a view of individual differences implicit in the term intelligences. New developments in imaging and genetics may make these connections more realistic.

Pre- and postmorbid singing of a patient with amusia due to a right-hemispheric infarction was analyzed acoustically. This particular patient had a premorbid tape recording of her own singing without accompaniment. Appropriateness of pitch interval and rhythm was evaluated based on ratios of pitch and duration between neighboring notes. The…

We evaluated hemispheric functions ipsilateral to the side of carotid endarterectomy (CEA) in patients with a severe stenosis in the left or right carotid artery. Assessments took place 1 day before and 3 months after CEA. Only right-handed males were included. Nineteen patients underwent surgery of the left carotid artery and 17 of the right.…

Shift of the cortical mechanisms of language from the usually dominant left to the non-dominant right hemisphere has been demonstrated in the presence of large brain lesions. Here, we report a similar phenomenon in a patient with a cavernoma over the anterolateral superior temporal gyrus associated with epilepsy. Language mapping was performed by…

Consistent with converging experimental evidence, we assume that foveal information is initially split across the two cerebral hemispheres. We have previously presented the SERIOL model of letter-position coding, which specifies how the resulting two halves of a letter string are integrated into an abstract representation of letter order. This…

The study of the neural basis of face perception is a major research interest today. This review traces its roots in monkey neuropsychology and neurophysiology beginning with the Kluver-Bucy syndrome and its fractionation and then continuing with lesion and single neuron recording studies of inferior temporal cortex. The context and consequence of…

This study focused on the relationship between school performance and performance on a dichotic listening (DL) task in dyslexic children. Dyslexia is associated with impaired phonological processing, related to functions in the left temporal lobe. DL is a frequently used task to assess functions of the left temporal lobe. Due to the predominance…

This science brief reports on a study that identified the effects of different experiences on critical periods of learning during early brain development. The study found that the presence of corticosterone in a part of the brain called the amygdala determined whether a normally painful experience was learned as an attractive or fearful event.…
