Constrained Spherical Deconvolution Tractography Reveals Cerebello-Mammillary Connections in Humans
<p>According to the classical view, the cerebellum has long been confined to motor control physiology; however, it has now become evident that it exerts several non-somatic features other than the coordination of movement and is engaged also in the regulation of cognition and emotion. In a previous diffusion-weighted imaging-constrained spherical deconvolution (CSD) tractography study, we demonstrated the existence of a direct cerebellum-hippocampal pathway, thus reinforcing the hypothesis of the cerebellar role in non-motor domains. However, our understanding of limbic-cerebellar interconnectivity in humans is rather sparse, primarily due to the intrinsic limitation in the acquisition of in vivo tracing. Here, we provided tractographic evidences of connectivity patterns between the cerebellum and mammillary bodies by using whole-brain CSD tractography in 13 healthy subjects. We found both ipsilateral and contralateral connections between the mammillary bodies, cerebellar cortex, and dentate nucleus, in line with previous studies performed in rodents and primates. These pathways could improve our understanding of cerebellar role in several autonomic functions, visuospatial orientation, and memory and may shed new light on neurodegenerative diseases in which clinically relevant impairments in navigational skills or memory may become manifest at early stages.</p>
Dog in the matrix: Envisioning countrywide connectivity conservation for an endangered carnivore
<ol> <li><span>Elevated rates of anthropogenic impacts on land-use regimes have pushed terrestrial megafauna to the brink of extinction. Consequently, it is critical to adopt conservation approaches that safeguard individual populations, while retaining connectivity among these populations. Conserving spatially structured populations of imperiled species at large scales is often complex; the past decades have therefore seen a rise in spatial conservation prioritization exercises aimed at shaping landscape-scale conservation programmes.</span></li> <li><span>We present a framework for informing nationwide connectivity conservation, linking ecological and administrative scales, to maximise relevance for management. We assessed connectivity of the endangered dhole <i>Cuon alpinus</i> among 155 potential source populations across India using a data-driven approach combined with graph and circuit theory. We used clustering algorithms to identify ecologically meaningful conservation landscapes; within each landscape, we identified priority source populations based on their connectedness, and quantified pixel-specific habitat <i>accessibility</i>. We superimposed administrative boundaries on our findings to provide conservation recommendations at this management-relevant scale.</span></li> <li><span>We first mapped potential dhole movement across India. Dhole populations fell within three primary clusters—Western and Eastern Ghats (WEG), Central Indian Landscape (CIL), and North-East India (NEI)—of which NEI had the highest forest cover, most diffuse connectivity, and lowest human density, while WEG had the highest protected area coverage, and overall connectedness. Within each conservation landscape we evaluated the relative importance of Protected Areas and accessibility<i> </i>to high-quality patches. Parts of the Eastern Ghats had low habitat accessibility, yet high potential for dhole landscape connectivity. In 114 identified administrative units of priority for habitat restoration, we highlight those with low accessibility, i.e., areas where restoration needs to be spatially targeted for maximum benefits.</span></li> <li> <i>Synthesis and applications</i>. We make recommendations for spatially-informed habitat restoration to enhance dhole connectivity in India, highlighting the importance of improving matrix permeability where dhole movement is currently restricted. More broadly, the framework we present is useful across species and management contexts, as it combines spatial and administrative scales to make ecologically-informed assessments of high relevance to management. Synergistically integrating species ecology, threats, and administrative considerations in connectivity conservation plans can enhance success of species conservation programmes.</li> </ol>
Maximum entropy model estimates functional connectivity
<p>Tools to estimate brain connectivity have been useful to improve our understanding of brain functioning. Reduced models ofcultured neurons are often used to study the behavior of neuronal networks, including functional connectivity and how it mightbe affected by external stimuli. Cultured neurons tend to be active in ensembles, and when pairs of neurons show significantsynchronicity in their firing patterns they are said to be functionally connected. The most common methods to infer functionalconnections are based on pair-wise cross correlation between activity patterns of (small groups of) neurons. However, thesemethods are not designed to be used during external stimulation, and they are relatively insensitive to inhibitory connections.Maximum Entropy (MaxEnt) models may provide a conceptually different method to infer functional connectivity, with thepotential benefit to estimate functional connectivity in the presence of an external stimulus and to infer excitatory as well asinhibitory connections. These models do not use pairwise comparison, but are based on probability distributions of sets ofneurons that are synchronously active in discrete time bins. We investigate the ability of the MaxEnt models to infer functionalconnectivity, using electrophysiological recordings fromin vitroneuronal cultures on micro electrode arrays. We comparefunctional connectivity as inferred by MaxEnt models to that obtained by conditional firing probabilities (CFP), an establishedcross-correlation based method. We show that MaxEnt models provide connectivity estimates that correlate well with CFPoutcomes. In addition, stimulus-induced connectivity changes were detected by MaxEnt models, and were of the samemagnitude as those detected by CFP.</p>

Data for: Widespread wood placement and regrading drive lateral connectivity and reworking of the channel and floodplain in a valley bottom reset to stage 0
<p>Valley bottom process reset, or the excavation of high surfaces and fill of incised channels combined with large wood addition, is a new method for creating multi-channel river-wetland corridors (also referred to as Stage 0 valley bottoms). Valley bottom process reset seeks to increase lateral flow and sediment connectivity to retain flow and sediment and kickstart geomorphic processes that may sustain aquatic and riparian habitats. This anthropogenic intervention provides an opportunity to examine relationships among wood-induced hydraulic roughness, valley bottom topography, and geomorphic processes such as overbank flow and sediment transport, avulsion, sediment retention, and pool scour. Here, I present a 6-year case study of a two-phase valley bottom process reset along Deer Creek, OR which indicates that kickstarting processes that reshape the floodplain requires a substantial increase in roughness and hydrologic connectivity. A first phase of construction enhanced hydrologic but not sediment connectivity, largely failing to kickstart avulsion and floodplain reworking even during a likely 2- to 5-year recurrence interval flood. A second, more intensive phase of construction substantially reduced the threshold flow necessary for overbank flow and incision of floodplain reworking, as evidenced by the occurrence of these processes after only a < 2-year recurrence interval flood. During this flood, a spatially distributed wood lattice rearranged into discrete jams that scoured pools, retained sediment, and drove geomorphically effective overbank flows. While valley bottom regrading likely contributed to these geomorphic effects, the spatial correlation between newly incised floodplain channels and areas of wood aggregation indicates a substantial role of wood-induced hydraulic roughness and channel blockage. Wood drove floodplain reworking via two mechanisms: in-channel wood jams backwatered and constructed flow into the floodplain, and small wood jams formed in the floodplain forest further constricted flow through nascent channels to facilitate channel incision.</p>

Historical biogeography and population genetic patterns observed here for Cardinal tetra, seem to be better explained by river capture, physical, or ecological barriers than due to the geographic distance.</span></span></p>
