The art and science of mindfulness
Antonella Sansone in Cultivating Mindfulness to Raise Children Who Thrive, 2020
There are striking links between mindful awareness, secure attachment and right-hemisphere involvement outcomes. Allan Schore’s work on attachment and development, which brings together neurological, biological and psychological studies, emphasises the fundamental role of the right brain in emotional regulation, healthy physiological and psychological development and healthy development of the immune system (Schore, 2003a, 2003b). Schore writes of non-conscious right-brain to right-brain communications (non-verbal) between parent and infant, which develop regulation (or dysregulation when it is poor) of the autonomic nervous system. The right hemisphere plays an important role in the development of emotional intelligence, creativity, empathy, autobiographical memory and self-reflection. Interestingly, interdisciplinary studies of creativity propose the right-brain hemisphere as the seat of creativity. The baby and young child need the mother’s right-brain involvement in their interactions to thrive physiologically, neurologically and psychologically. She needs right-brain to right-brain communications to learn empathy; compassion; awareness of her own emotions, thus of others’ emotions; and self-reflection and to develop autobiographical memory.
Overview
Roger Neighbour in The Inner Consultation, 2018
B1 ‘How people learn’. This section begins with a reappraisal of the processes involved in human learning. In teaching, the emphasis in the past has been almost exclusively on cultivating the analytic and intellectual faculties broadly associated in neurophysiological terms with the ‘dominant’ (usually the left) cerebral hemisphere. Yet increasingly we are becoming aware of how much the ‘non-dominant’ (usually the right) hemisphere contributes to perception, understanding, intuition and learning. The right hemisphere learns in different ways from the left, but both hemispheres need to be involved in the learning of a complex behavioural skill such as consulting. This book combines left and right hemisphere teaching techniques in order to develop skills at both the conscious and unconscious levels.
Correlations Between Different Aspects of Lateralization, and with Gender
Robert Miller in Axonal Conduction Time and Human Cerebral Laterality, 2019
In auditory tests of lateralization a variety of the relationships with handedness are reported. Several studies show, as with visual tests, that there is a reduced left hemisphere advantage in left handers. Zurif and Bryden (1969), using two different dichotic tests found that right handers, and left handers without familiar sinistrality had the expected left hemisphere advantage. Left handers with a family history of left handedness were equally divided between left and right hemisphere dominance. In other words, as with several results with visual stimuli, there was a shift to the right hemisphere but no overall majority of right hemisphere dominance even in this selected group. A similar result was obtained with accuracy of report as the dependent measures as when using the percentage of subjects with advantage to each hemisphere. Shankweiler and Studdert-Kennedy (1975) found that the degree of right ear advantage for CV syllable recognition correlated with measures of the degree of right handedness. Natale (1977) used a dichotic listening test involving short rhythms, with recognition of already-presented rhythms as the response measure. Male and female subjects were graded according to their degree of handedness. A right ear advantage was detected correlating in degree with degree of dexterity. Graves (1983) and Iaccino and Sowa (1989) also found that right ear advantages in dichotic tests were reduced in left handers.

The cerebral hemispheres presented different activation behavior through exposure to VR, given their complexity and inter-hemispheric specialization. In particular, the present study showed a significant greater activation in the right hemisphere. The right hemisphere is responsible for processing new stimuli, while the left hemisphere works with assimilated information. In this sense, considering the learning process, with the acquisition of new information and ability, brain activity is generally larger in the right hemisphere, and the left hemisphere becomes more activated after learning [1]. Although the present study has not been proposed to investigate learning, the brain activity pattern observed during the virtual task resembles the one observed during the beginning of the learning process. This might be due to the virtual environment promotes a great cognitive demand and high concentration, allowing subjects to experience an activity in a rich environment, and different from what is experienced in their daily lives.
Hippocampal functional network: The mediating role between obsession and anxiety in adult patients with obsessive-compulsive disorder

Our study results suggested that the brain regions (mainly in right hemisphere), including PFC (mainly in the dorsolateral side) and IPG, were positively associated with obsession. The PFC has been suggested to play an important role in emotional processing and inhibitory control (Moon and Jeong 2015). Abnormal activation of the PFC may be associated with inhibitory control deficit and emotional dysregulation. Moreover, the frontal–hippocampal pathway plays a key role in suppressing intrusive thoughts (Schmitz et al. 2017). These findings provided evidence that the dysfunction of the frontal–hippocampal pathway makes patients with OCD unable to resist intrusive thoughts. Moreover, the right hemisphere was found to play an important role in emotional processing (Noesselt et al. 2005).
Examining Interhemispheric PFC Connectivity during AUD Abstinence with Multilevel Modeling
Published in Alcoholism Treatment Quarterly, 2022
Spencer Bradshaw, Adam Jones, Rebecca Lucero Jones, Sterling Shumway, Thomas Kimball
The functional interhemispheric PFC connectivity found in this study may infer that processing alcohol-related cues with an intent to remain abstinent becomes at some level a “high-demand” task requiring greater processing resources (Mumtaz et al., 2018). It is interesting that the functional interhemispheric connectivity found was not empirically distinguishable by hemisphere (left or right). These results indicate that it may be the connectivity or interhemispheric communication itself that is important to processing alcohol-related cues. The left hemisphere is believed to be associated with approach processing and the right hemisphere with avoidance processing (Banich, 2000; Tasman et al., 2015); however, perhaps such specialization is not as important as long as interhemispheric communication is occurring. Additionally, previous research has shown unilateral hyperactivation responses to substance-related stimuli during active addiction (Goldstein & Volkow, 2011) and the results from this study may suggest that a bilateral sharing of tasks and responsibilities across hemispheres is restoring during abstinence. However, longitudinal data is needed to confirm this interpretation.
