"No civil discourse, no cooperation; misinformation, mistruth." These were the words of former Facebook Vice President Chamath Palihapitiya who publicly expressed his regret in a 2017 interview over his role in co-creating Facebook. Palihapitiya shared that social media is ripping apart the social fabric of society and he also sounded the alarm regarding social media’s unavoidable global impact. He is only one of social media’s countless critics. The more disturbing issue resides in the empirical evidence supporting such notions. At least 95% of adolescents own a smartphone and spend an average time of two to four hours a day on social media. Moreover, 91% of 16-24-year-olds use social media, yet youth rate Instagram, Facebook, and Twitter as the worst social media platforms. However, the social, clinical, and neurodevelopment ramifications of using social media regularly are only beginning to emerge in research. Early research findings show that social media platforms trigger anxiety, depression, low self-esteem, and other negative mental health effects. These negative mental health symptoms are commonly reported by individuals from of 18-25-years old, a unique period of human development known as emerging adulthood. Although emerging adulthood is characterized by identity exploration, unbounded optimism, and freedom from most responsibilities, it also serves as a high-risk period for the onset of most psychological disorders. Despite social media’s adverse impacts, it retains its utility as it facilitates identity exploration and virtual socialization for emerging adults. Investigating the “user-centered” design and neuroscience underlying social media platforms can help reveal, and potentially mitigate, the onset of negative mental health consequences among emerging adults. Effectively deconstructing the Facebook, Twitter, and Instagram (i.e., hereafter referred to as “The Big Three”) will require an extensive analysis into common features across platforms. A few examples of these design features include: like and reaction counters, perpetual news feeds, and omnipresent banners and notifications surrounding the user’s viewport. Such social media features are inherently designed to stimulate specific neurotransmitters and hormones such as dopamine, serotonin, and cortisol. Identifying such predacious social media features that unknowingly manipulate and highjack emerging adults’ brain chemistry will serve as a first step in mitigating the negative mental health effects of today’s social media platforms. A second concrete step will involve altering or eliminating said features by creating a social media platform that supports and even enhances mental well-being.

Neurological manifestations may be more prominent and have a larger role in ankylosing spondylitis than previously thought. Ankylosing Spondylitis is a rheumatic disease primarily identified by its autoinflammatory characteristics and is highly associated with the HLA-B27 gene. While it’s cause is not yet fully understood and it’s symptoms widely vary, neurological impairment is not uncommon. The neurological manifestations of Ankylosing Spondylitis include but are not limited to pain sensitization, altered brain phenotype, and disrupted cardiac conduction. Central and peripheral nervous system involvement may be more significant than previously thought and have the potential to cause demyelinating diseases, spinal cord, and nerve root injuries. Altered connectivity throughout various regions within the brain further exemplify the need for a better understanding of the disease and better treatment development. Higher instances of depression and dementia were also reported and coincide with not only a less active lifestyle, but altered brain activity. Studies on cardiac conduction and arrhythmias in AS patients revealed parasympathetic and sympathetic nervous system dysregulation. These studies have explored the possibility of new targets for treatment involving cardiac mechanisms. Treatments for diseases of a similar suspected pathology, new prospective targets for therapy, and a more thorough understanding of current treatments for the disease may be the key in providing more substantial relief. By further investigation in the role of the nervous system in Ankylosing Spondylitis, the disease may become more manageable for patients and greatly increase quality of life in the future.

Parkinson’s disease (PD) is a debilitating neurodegenerative disease characterized primarily by physical impairments such as tremors, poor balance, and bradykinesia; however, some individuals with PD will additionally experience numerous nonmotor symptoms such as dementia, depression, and sleep disturbances amongst various other life-altering ailments. Two of the key pathological hallmarks of PD include the death of melanated dopaminergic neurons in the nigrostriatal pathway and the accumulation of Lewy bodies, which are primarily composed of aggregates of the protein α-synuclein (α-syn). Interestingly, members of the chitinase protein family, namely chitinase-3-like protein-1 (L1), have heightened concentrations in a number of neurodegenerative diseases other than PD. To investigate the specific role L1 plays in PD etiology, we evaluated if astrocytic L1 expression was elevated in postmortem brain tissue of PD patients as well as in an α-syn overexpression rat model, and further tested if manipulating astrocytic-specific L1 expression correlated with neuroinflammation and nigral neuronal degeneration in the model. Preliminary histological analysis has shown increased levels of L1 expression in the α-syn model before neuronal loss occurs, and in human tissue, L1 was found to be significantly increased in the postmortem tissue of individuals with PD versus non-diseased controls. Investigations in identifying an astrocytic-specific virus capsid and manipulating L1 expression in the α-syn model are ongoing. This preliminary data thus far supports that increased astrocytic expression of L1 is associated with PD pathology.

The cerebellum is recognized for its role in motor movement, balance, and more recently, social behavior. Cerebellar injury at birth and during critical periods reduces social preference in animal models and increases the risk of autism in humans. Social behavior is commonly assessed with the three-chamber test, where a mouse travels between chambers that contain a conspecific and an object confined under a wire cup. However, this test is unable to quantify interactive behaviors between pairs of mice, which could not be tracked until the recent development of machine learning programs that track animal behavior. In this study, both the three-chamber test and a novel freely-moving social interaction test assessed social behavior in untreated male and female mice, as well as in male mice injected with hM3Dq (excitatory) DREADDs. In the three-chamber test, significant differences were found in the time spent (female: p < 0.05, male: p < 0.001) and distance traveled (female: p < 0.05, male: p < 0.001) in the chamber with the familiar conspecific, compared to the chamber with the object, for untreated male, untreated female, and mice with activated hM3Dq DREADDs. A social memory test was added, where the object was replaced with a novel mouse. Untreated male mice spent significantly more time (p < 0.05) and traveled a greater distance (p < 0.05) in the chamber with the novel mouse, while male mice with activated hM3Dq DREADDs spent more time (p<0.05) in the chamber with the familiar conspecific. Data from the freely-moving social interaction test was used to calculate freely-moving interactive behaviors between pairs of mice and interactions with an object. No sex differences were found, but mice with excited hM3Dq DREADDs engaged in significantly more anogenital sniffing (p < 0.05) and side-side contact (p < 0.05) behaviors. All these results indicate how machine learning allows for nuanced insights into how both sex and chemogenetic excitation impact social behavior in freely-moving mice.

High-grade gliomas are highly aggressive central nervous system (CNS) malignancies with high fatality rates if left untreated. There is currently a lack of reliable diagnostic tools to characterize the diffuse cell populations commonly found in these tumors. Here, we report that electrochemical impedance spectroscopy (EIS) can be used in an in vitro system to analyze changes in the impedance contributed by the extracellular matrix (ECM) of two glioblastoma cell lines: GBM 22 and GBM 115. EIS was more effective at resolving differences in impedance from GBM 115 cells than GBM 22 cells, which depended on both cell confluency and frequency. However, differences in impedance were more apparent from the supernatant when the cells were removed in both cell lines. Analysis of the PC12 and either of the GBM cell line co-cultures yielded highly statistically significant differences between all comparisons of cell confluencies and frequency steps. These results illustrate that EIS can be an effective instrument for characterizing the ECM surrounding glioblastoma cells, providing insight into the cellular behavior of these oncogenic cells.
