EEG Wave Value Differentiation Explaining Different Stages of Parkinson’s Disease

Author: Ishmam Khan, Class of 2025 Figure: Parkinson’s is a detrimental neurodegenerative disease that affects patients at varying degrees of severity As neurodegenerative diseases like Parkinson’s disease (PD) progress, insights into brain changes become crucial for early diagnoses and effective interventions. In a recent study, Pappalettera et al. at Stony Brook University utilized Approximate Entropy (ApEn) analysis to compare the complex brain signals that occur … Continue reading EEG Wave Value Differentiation Explaining Different Stages of Parkinson’s Disease

Non-planned and impulsive suicide attempts associated with low activity of frontal brain 

By: Jessica George, Class of 2024 Figure 1: Global frontal brain activity may be a biomarker for non-planned or impulsive suicide attempts Suicide is a serious public health concern and one of the leading causes of death worldwide. One of the major challenges in preventing suicide is the frequent non-planned or impulsive nature of suicidal behavior, leaving little opportunity for intervention. Therefore, it is essential … Continue reading Non-planned and impulsive suicide attempts associated with low activity of frontal brain

Intrinsic Biases in Maternal EEG/ERP Research Undermine Racial Representation

Vignesh Subramanian ’24 The use of electroencephalography (EEG) and event-related potentials (ERPs) – two methods of recording brain waves to measure continuous and stimulus-based electrical activity, respectively – is most common in the diagnosis of brain disorders. However, EEG/ERP methodology is also used to monitor the timing of cognitive functions during periods of stress or development. EEG’s high temporal resolution allows for the observation of … Continue reading Intrinsic Biases in Maternal EEG/ERP Research Undermine Racial Representation

EEG Analysis Reveals Association Between Parkinson’s Disease with Visual Hallucinations and Epileptic Discharges

Jessica George ’24 Psychosis in Parkinson’s Disease (PD) is characterized by visual hallucinations (VHs). These VHs have a significant impact on patient’s lives and serve as a reliable predictor for future nursing home institutionalization. Several disorders such as Charles Bonnet syndrome and temporal lobe epilepsy have similar features to those of PD VHs. In the aforementioned disorders, EEG analysis revealed epileptiform discharges, which led researchers … Continue reading EEG Analysis Reveals Association Between Parkinson’s Disease with Visual Hallucinations and Epileptic Discharges

Neuronal Firing in Thalamus is Key to Restoring Post-TBI Consciousness

Vignesh Subramanian ’24 Traumatic brain injury (TBI) is a form of acquired brain disability caused by an external force exerted against the head. The causative trauma is typically severe enough to result in loss of consciousness and the conditions under which consciousness returns remain unclear. Clinical practice uses complex electroencephalography (EEG) activity to predict its return and level, predicated on the assumption that neuronal firing … Continue reading Neuronal Firing in Thalamus is Key to Restoring Post-TBI Consciousness

Accidental EEG Recording of Dying Patient Offers Tentative Glimpse into Our Final Moments

Jessica George ’24 In our relentless pursuit for knowledge, perhaps one of the most perplexing questions to humankind is what happens when we die. Several individuals who have undergone near-death experiences (NDE) describe their “life flashing before their eyes.” There is also the classical theory of a hypoactive brain during the end stages of life, where the brain ceases all electrical activity. Contrary to this … Continue reading Accidental EEG Recording of Dying Patient Offers Tentative Glimpse into Our Final Moments

Consuming Dark Chocolate Linked to Stress Reduction and Inflammation

By Meenu Johnkutty ‘21 There may be new incentive to indulge in your chocolate cravings! Though many studies have explored the benefits of consuming dark chocolate, a recent study at the Loma Linda University Adventist Health Sciences Center is the first to analyze the benefits of consuming specific quantities of particular types of dark chocolate. The study, led by Dr. Berk, the associate dean of … Continue reading Consuming Dark Chocolate Linked to Stress Reduction and Inflammation
