Rapid generation of conditional knockout mice using the CRISPR-Cas9 system and electroporation for neuroscience research.

The Cre/LoxP-based conditional knockout technology is a powerful tool for gene function analysis that allows region- and time-specific gene manipulation. However, inserting a pair of LoxP cassettes to generate conditional knockout can be technically challenging and thus time- and resource-consuming. This study proposes an efficient, low-cost method to generate floxed mice using in vitro fertilization and the CRISPR-Cas9 system over two consecutive generations. This method allowed us to produce floxed mice targeting exons 5 and 6 of CaMK1 in a short period of 125 days, using only 16 mice. In addition, we directly edited the genome of fertilized eggs of mice with our target genetic background, C57BL/6 N, to eliminate additional backcrossing steps. We confirmed that the genome of the generated floxed mice was responsive to the Cre protein. This low-cost, time-saving method for generating conditional knockout will facilitate comprehensive, tissue-specific genome analyses.

Two decades of neuroscience publication trends in Africa.

Neuroscience research in Africa remains sparse. Devising new policies to boost Africa's neuroscience landscape is imperative, but these must be based on accurate data on research outputs which is largely lacking. Such data must reflect the heterogeneity of research environments across the continent's 54 countries. Here, we analyse neuroscience publications affiliated with African institutions between 1996 and 2017. Of 12,326 PubMed indexed publications, 5,219 show clear evidence that the work was performed in Africa and led by African-based researchers - on average ~5 per country and year. From here, we extract information on journals and citations, funding, international coauthorships and techniques used. For reference, we also extract the same metrics from 220 randomly selected publications each from the UK, USA, Australia, Japan and Brazil. Our dataset provides insights into the current state of African neuroscience research in a global context.

Building brain capital.

Brains are indispensable drivers of human progress. Why not invest more heavily in them? We seek to place Brain Capital at the center of a new narrative to fuel economic and societal recovery and resilience.

Baseline Resilience and Posttraumatic Symptoms in Dyads of Neurocritical Patients and Their Informal Caregivers: A Prospective Dyadic Analysis.

BACKGROUND: Admission to a neuroscience intensive care unit (Neuro-ICU) is sudden and often traumatic for both patients and their informal caregivers. No prior studies have assessed prospectively risk and resiliency factors for chronic posttraumatic symptoms, as well as the potential interdependence between patients' and caregivers' symptoms over time. OBJECTIVE: To analyze the impact of baseline resiliency factors on symptoms of posttraumatic stress (PTS) longitudinally in dyads of patients admitted to the Neuro-ICU and their primary family caregivers. METHODS: We recruited dyads (M = 108) of patients admitted to the Neuro-ICU (total N = 102) and their family caregivers (total N = 103). Dyads completed self-report assessments of PTS and resiliency factors (mindfulness and coping) at baseline in the Neuro-ICU. PTS was measured again at 3- and 6-month follow-up. RESULTS: Clinically significant PTS symptoms were high at baseline in both patients (20%) and caregivers (16%) and remained high through 6 months (25% in patients; 14% in caregivers). Actor-partner interdependence modeling demonstrated that severity of PTS symptoms was predictive of PTS symptoms at subsequent time points (P < 0.001). High baseline mindfulness and coping predicted less severe PTS symptoms in patients and caregivers (P < 0.001) at all time points. Own degree of PTS symptoms at 3 months predicted worse PTS symptoms in one's partner at 6 months, for both patients and caregivers (P = 0.02). CONCLUSIONS: Findings highlight the need to prioritize assessment and treatment of PTS in Neuro-ICU patients and their informal caregivers through a dyadic approach.

Survey on Willingness to Pay for Life-Saving Treatment, Functional Recovery, and Cosmesis in a Neuroscience Outpatient Clinic Setting in Singapore.

BACKGROUND: Neurologic disorders impose a heavy burden on healthcare in Singapore. To date, no data on the willingness to pay (WTP) for neurologic treatments has been reported in the local population. OBJECTIVES: We aimed to quantify the value of various health domains to neuroscience patients and their caregivers by comparing their WTP for different types of treatments. METHODS: A questionnaire using a mixed open-ended and closed-ended contingent valuation method was developed to elicit WTP and self-administered by 112 visitors to a neuroscience outpatient clinic. The WTP for treatments in 3 health domains (advanced restoration of function, life extension, and cosmesis) was evaluated and compared. Subgroup regression analysis was performed to investigate the impact of demographic and socioeconomic factors. RESULTS: Treatment that improved cosmesis had the highest median WTP of Singapore dollar (SGD) 35 000, followed by treatment that provided 1 year of life extension (SGD 20 000) and 1 year of advanced restored function (SGD 10 000; P < .001). Respondents with a university education were willing to pay as much as 2 to 3 times of those without across all health domains. CONCLUSION: This is the first study to provide data on how different health domains are valued by neuroscience patients and caregivers in our population. Respondents valued treatment that restored or improved their physical appearances the most. These findings could contribute to future policies on the improvement of neuroscience care.

The Costs of Reproducibility.

Improving the reproducibility of neuroscience research is of great concern, especially to early-career researchers (ECRs). Here I outline the potential costs for ECRs in adopting practices to improve reproducibility. I highlight the ways in which ECRs can achieve their career goals while doing better science and the need for established researchers to support them in these efforts.

Advancing Neuroscience Research in Africa: Invertebrate Species to the Rescue.

Neuroscience research and training in many African countries are difficult due to funding and infrastructure deficit. This has resulted in few neuroscientists within Africa. However, invertebrates such as Drosophila and Caenorhabditis elegans could provide the perfect answer to these difficulties. These organisms are cheap, easy to handle and offer a comparable advantage over vertebrates in neuroscience research modeling because they have a simple nervous system and exhibit well-defined behaviors. Studies using invertebrates have helped to understand neurosciences and the complexes associated with it. If Africa wants to catch up with the rest of the world in neuroscience research, it needs to employ this innovative cost-effective approach in its research. To improve invertebrate neuroscience within the Africa continent, the authors advocated the establishment of invertebrate research centers either at regional or national level across Africa. Finally, there is also a need to provide public funding to consolidate the gains that have been made by not-for-profit international organizations over the years.

Orbitofrontal Cortex: A Neural Circuit for Economic Decisions.

Economic choice behavior entails the computation and comparison of subjective values. A central contribution of neuroeconomics has been to show that subjective values are represented explicitly at the neuronal level. With this result at hand, the field has increasingly focused on the difficult question of where in the brain and how exactly subjective values are compared to make a decision. Here, we review a broad range of experimental and theoretical results suggesting that good-based decisions are generated in a neural circuit within the orbitofrontal cortex (OFC). The main lines of evidence supporting this proposal include the fact that goal-directed behavior is specifically disrupted by OFC lesions, the fact that different groups of neurons in this area encode the input and the output of the decision process, the fact that activity fluctuations in each of these cell groups correlate with choice variability, and the fact that these groups of neurons are computationally sufficient to generate decisions. Results from other brain regions are consistent with the idea that good-based decisions take place in OFC and indicate that value signals inform a variety of mental functions. We also contrast the present proposal with other leading models for the neural mechanisms of economic decisions. Finally, we indicate open questions and suggest possible directions for future research.
