Increased Excitatory Synaptic Transmission of Dentate Granule Neurons in Mice Lacking PSD-95-Interacting Adhesion Molecule Neph2/Kirrel3 during the Early Postnatal Period
No full textCopy number variants and point mutations of NEPH2 (also called KIRREL3) gene encoding an immunoglobulin (Ig) superfamily adhesion molecule have been linked to autism spectrum disorders, intellectual disability and neurocognitive delay associated with Jacobsen syndrome, but the physiological roles of Neph2 in the mammalian brain remain largely unknown. Neph2 is highly expressed in the dentate granule (DG) neurons of the hippocampus and is localized in both dendrites and axons. It was recently shown that Neph2 is required for the formation of mossy fiber filopodia, the axon terminal structure of DG neurons forming synapses with GABAergic neurons of CA3. In contrast, however, it is unknown whether Neph2 also has any roles in the postsynaptic compartments of DG neurons. We here report that, through its C-terminal PDZ domain-binding motif, Neph2 directly interacts with postsynaptic density (PSD)-95, an abundant excitatory postsynaptic scaffolding protein. Moreover, Neph2 protein is detected in the brain PSD fraction and interacts with PSD-95 in synaptosomal lysates. Functionally, loss of Neph2 in mice leads to age-specific defects in the synaptic connectivity of DG neurons. Specifically, Neph2−/− mice show significantly increased spontaneous excitatory synaptic events in DG neurons at postnatal week 2 when the endogenous Neph2 protein expression peaks, but show normal excitatory synaptic transmission at postnatal week 3. The evoked excitatory synaptic transmission and synaptic plasticity of medial perforant pathway (MPP)-DG synapses are also normal in Neph2−/− mice at postnatal week 3, further confirming the age-specific synaptic defects. Together, our results provide some evidence for the postsynaptic function of Neph2 in DG neurons during the early postnatal period, which might be implicated in neurodevelopmental and cognitive disorders caused by NEPH2 mutations.

Perspective: Uniform switching of artificial synapses for large-scale neuromorphic arrays
No full textResistive random-access memories are promising analog synaptic devices for efficient bio-inspired neuromorphic computing arrays. Here we first describe working principles for phase-change random-access memory, oxide random-access memory, and conductive-bridging random-access memory for artificial synapses. These devices could allow for dense and efficient storage of analog synapse connections between CMOS neuron circuits. We also discuss challenges and opportunities for analog synaptic devices toward the goal of realizing passive neuromorphic computing arrays. Finally, we focus on reducing spatial and temporal variations, which is critical to experimentally realize powerful and efficient neuromorphic computing systems

Grave of noted author
No full textThis undated article is a memorial to Horace Kephart (1862-1931), a noted naturalist, woodsman, journalist, and author. In 1904, he left his work as a librarian in St. Louis and permanently moved to western North Carolina. His popular book, “Camping and Woodcraft” was first published 1906; the 1916/1917 edition is considered a standard manual for campers after almost a century of use. Living and working in a cabin on Hazel Creek in Swain County, Kephart began to document life in the Great Smoky Mountains, producing “Our Southern Highlanders” in 1913. Throughout his life, Kephart wrote many articles supporting the Great Smoky Mountains National Park.GRAVE OF NOTED AUTHOR—On a hillside overlooking Bryson City and with the Great Smoky
Mountains National park in view in the distance, a huge boulder marks the grave of Horace Kephart, of
Bryson City, author of "Our Southern Highlanders" and other books, and who was an active advocate of a
national park in the Smokies. The highest peak of the mountains in the distance is Mount Kephart, named
in honor of the author. The boulder that marks the grave in Bryson City cemetery was brought from the
Great Smokies as a CCC project
Crocker Range National Park, Sabah, as a refuge for Borneo’s montane herpetofauna
No full textCrocker Range National Park in Sabah (East Malaysia), northern Borneo, is an exceptional area for herpetological diversity. Inventories of the Park are incomplete, but show high diversity, as well as regional endemicity shared with the adjacent and more well-known Gunung Kinabalu National Park. The montane ecosystem of the Range offers refuge for a number of rare herpetofaunal taxa, including Stoliczkia borneensis, Rhabdophis murudensis, Oligodon everetti, Philautus bunitus, Ansonia anotis, Sphenomorphus aesculeticola, and undescribed species of squamates of the genera Sphenomorphus and Gongylosoma. The 59 species of amphibians and 45 species of reptiles now recorded from the Range represent 39 and 16.2 per cent of the total Bornean amphibian and reptile fauna, respectively. The high levels of deforestation of the surrounding regions of Borneo, particularly lowland rainforests, highten the importance of protection of primary forests of northern Borneo’s Crocker Range

Sustainable ecotourism in the village of Khiriwong and the Khao Luang National Park, Thailand
No full textPlan BSustainable ecotourism is often considered to be effective for supporting the local communities’ economy and promoting the conservation of protected areas in developing countries. By establishing economic benefits for impoverished villagers or their communities, sustainable ecotourism is utilized to encourage local guardianship of natural resources. To assess sustainable ecotourism’s impact on the revenue of local residents in the Village of Khiriwong and the Khao Luang National Park, and its effects on the environmental preservation of the Khao Luang National Park in Nakhon Si Thammarat Province, Thailand, the researcher randomly conducted surveys of then visitors’ attitudes about rewarding experiences during their village and park visits. Biologists and Ecologists were interviewed about sustainable ecotourism’s role in supporting environmental preservation in the village and national park. Also, local residents in the village, as beneficiaries, were asked by the researcher to provide their perceptions about the relationship of sustainable ecotourism to cultural disruption. To examine the sustainable ecotourism in the village and the national park and learn whether it provides the visitors with rewarding experiences, a qualitative research was conducted in the Village of Khiriwong and the Khao Luang National Park at Karom Unit, Nakhon Si Thammarat Province, Thailand. The visitors were asked to state their opinions via questionnaires after their village and national park visits. Sustainable ecotourism in the Village of Khiriwong and the Khao Luang National Park were investigated as to whether it helped support environmental conservation. The national park staff and the villagers were randomly selected for personal interviews by the researcher. A comprehensive literature review was conducted about tourism in protected areas, the tourists and ecotourists, host community and sustainable ecotourism, local attitudes, economic impacts, social impacts and environmental impacts caused by tourism, carrying capacity, tourism and sustainable development, and tourism and recreation in remote and sensitive destinations. The research methodology in this study centered upon on-site field observation and mailed and personal interview surveys. Visitors to the village and the national park were asked to complete the survey questionnaires, which were designed and prepared in Thai and English versions. Experts in environmental biology and ecology and local residents were interviewed by the researcher in person with the questions in both Thai and English. The survey was taken during the two-month stay in the village from September 6th to November 6th, 2000. After completing the data collection, the researcher brought the raw results to the United States of America for compilation and analysis. The survey information was analyzed to describe the sustainable ecotourism in the Village of Khiriwong and the Khao Luang National Park in terms of rewarding experiences, environmental preservation, social and cultural impacts and economic benefits. Suggestions and recommendations about maintaining and improving sustainable ecotourism in the destinations were established by the findings. The findings were evaluated using proposed sustainable ecotourism elements in the village and park. Besides providing visitors rewarding experiences, sustainable ecotourism became an instrument in natural resource conservation such as water use. The village tourism brought benefits and income to most local residents with tourism involvement. The local residents agreed with the village and park tourism that they needed more education to support the village and park tourism. Tourism improved access, stimulated new services and conveniences like roads but social problems also could be found. Numerous implications for concessions, national park and protected areas management, local participation, relationships between the village and park, environmental and cultural impacts caused by tourism were discussed
