The Posterior Cerebellum is Involved in Constructing Social Action Sequences: An fMRI Study (2019)

January 13, 2022 by Megan Berg.
Previous research with healthy adults— using fMRI technology—has demonstrated strong activation between the cerebellum and cerebral cortex during the understanding of social events and behaviors. This study wanted to expand upon Van Overwalle et al (2019) research that used picture sequencing (using cartoon drawings) with “false belief ” tasks. These tasks require a person to […]

Water Supplementation After Dehydration Improves Judgment and Decision-Making Performance (2019)

January 13, 2022 by Megan Berg.
The authors had 4 hypotheses for this study: (Hypothesis 1) water consumption would improve sustained attention and executive function test results; (Hypothesis 2) water consumption should also be extended to improve judgment and decision-making tasks; (Hypothesis 3) attention and executive function accuracy will correlate with judgment and decision- making tasks; (Hypothesis 4) The judgement and […]

January 13, 2022 by Megan Berg.
This study had 20 participants (9 females) with PD—with no signs of dementia—and 20 elderly healthy controls (9 females). Both the Mini-Mental Status Examination and Montreal Cognitive Assessment were given to all the participants and everyone scored >25. All of the participants were right- handed and there were no significant differences with age. The participants […]

Self-Focused Processing After Severe Traumatic Brain Injury: Relationship to Neurocognitive Symptoms (2018)

January 13, 2022 by Megan Berg.
Severe TBI can negatively impact a person’s capacity for self-reflection and emotional regulation. Self-reflection was broken down into rumination and reflection which are both used to cope with stress or problem solve. Rumination is the negative thoughts or perception of self in regards to losses, threats, or injustices. If this negative self-talk continues with an […]

January 13, 2022 by Megan Berg.
This prospective cross-sectional research study had 251 patients with severe brain injuries and they had an MRI completed within the first month of the injury. The authors defined severe head trauma as Glasgow Coma Scale (GCS) of 8 or less during admission with non-surgical resuscitation or the GCS deteriorated to 8 or less during the […]

Working Memory and Executive Function Decline across Normal Aging, Mild Cognitive Impairment, and Alzheimer’s Disease (2015)

January 13, 2022 by Megan Berg.
Working memory “promotes active short-term maintenance of information for later access and manipulation.” It can be broken into auditory and visual working memory. The phonological loop is responsible for auditory working memory and the ability to support language comprehension. The visuospatial sketchpad is responsible for visual working memory and supporting visuospatial reasoning. For adults over […]

Impact of Chronic Hyponatremia on Neurocognitive and Neuromuscular Function (2018)

January 13, 2022 by Megan Berg.
This study had 19 patient’s from an outpatient clinic of the University Hospital of Wurzbug with documented chronic mild (sodium level 130-134 mmol/L) or moderate (serum sodium level 121-129 mmol/ L) hyponatremia. Of the 19 patients, there were 11 females, 8 males, and their ages ranged from 45 to 79 years of age. There were […]

Training-Dependent Structural Neuroplasticity in Brain-Injured Patients (2018)

January 13, 2022 by Megan Berg.
Two journal databases were used to find structural MRI studies used to measure neuroplasticity from training or rehabilitation treatment for individuals with an acquired brain injury (ABI). 1634 research articles were initially found and after the inclusion criteria was applied, 25 articles were identified for this study. The inclusion criteria consisted of 1) the participants […]
