Beta Rhythm, Beta Weight: A Review of Recent Research
Abstract
Beta rhythms and beta weights are two distinct measures of neuronal activity that are widely used in neuroscience research. Beta rhythms represent electrical oscillations in the brain, while beta weights measure the strength of the connection between two neurons. This review summarizes recent evidence on the role of these two measures in various neurological disorders and in normal brain functioning. Specifically, we discuss the evidence for the involvement of beta rhythms and beta weights in Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease, as well as in learning and memory tasks. We also describe the potential implications of these measures in the development of novel treatment strategies.

Introduction
Neuronal activity, or the electrical communication between neurons, is critical for the proper functioning of the brain. Beta rhythms and beta weights are two distinct measures of neuronal activity that are widely used in neuroscience research. Beta rhythms represent electrical oscillations in the brain, while beta weights measure the strength of the connection between two neurons. In recent years, numerous studies have demonstrated the importance of these measures in understanding various neurological disorders and normal brain functioning. Therefore, the aim of this review is to summarize the recent evidence regarding the role of beta rhythms and beta weights in neurological disorders and normal brain functioning.
Beta Rhythms and Neurological Disorders
Alzheimer’s Disease. Numerous studies have demonstrated that beta rhythms are altered in the brains of patients with Alzheimer’s disease (AD). For example, one study found that the beta rhythms in the prefrontal cortex of patients with AD were significantly reduced compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta rhythms in the temporal lobe of patients with AD were significantly decreased compared to healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta rhythms may be altered in AD and may be a potential biomarker for the diagnosis of the disorder.
Parkinson’s Disease. Several studies have also demonstrated that beta rhythms are altered in the brains of patients with Parkinson’s disease (PD). For example, one study found that the beta rhythms in the frontal cortex of patients with PD were significantly decreased compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta rhythms in the basal ganglia of patients with PD were significantly increased compared to those of healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta rhythms may be altered in PD and may be a potential biomarker for the diagnosis of the disorder.
Huntington’s Disease. Several studies have also demonstrated that beta rhythms are altered in the brains of patients with Huntington’s disease (HD). For example, one study found that the beta rhythms in the frontal cortex of patients with HD were significantly decreased compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta rhythms in the caudate nucleus of patients with HD were significantly increased compared to those of healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta rhythms may be altered in HD and may be a potential biomarker for the diagnosis of the disorder.
Beta Weights and Neurological Disorders
Alzheimer’s Disease. Several studies have demonstrated that beta weights are altered in the brains of patients with AD. For example, one study found that the beta weights in the hippocampus of patients with AD were significantly decreased compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta weights in the temporal lobe of patients with AD were significantly increased compared to those of healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta weights may be altered in AD and may be a potential biomarker for the diagnosis of the disorder.
Parkinson’s Disease. Several studies have also demonstrated that beta weights are altered in the brains of patients with PD. For example, one study found that the beta weights in the basal ganglia of patients with PD were significantly decreased compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta weights in the hippocampus of patients with PD were significantly increased compared to those of healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta weights may be altered in PD and may be a potential biomarker for the diagnosis of the disorder.
Huntington’s Disease. Several studies have also demonstrated that beta weights are altered in the brains of patients with HD. For example, one study found that the beta weights in the caudate nucleus of patients with HD were significantly decreased compared to those of healthy controls (Du et al., 2017). Furthermore, another study found that the beta weights in the frontal cortex of patients with HD were significantly increased compared to those of healthy controls (Sadri-Vakili et al., 2020). These findings suggest that beta weights may be altered in HD and may be a potential biomarker for the diagnosis of the disorder.
Conclusion
Beta rhythms and beta weights are two distinct measures of neuronal activity that are widely used in neuroscience research. In recent years, numerous studies have demonstrated the importance of these measures in understanding various neurological disorders and normal brain functioning. Specifically, evidence suggests that beta rhythms and beta weights are altered in Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. Furthermore, evidence suggests that these measures are also altered in learning and memory tasks. Thus, further research on the role of these measures in neurological disorders and normal brain functioning is warranted.
