Time-lapse microscopy, retrospective immunohistochemistry, and cultured hippocampal neurons were used to determine the time frame of individual glutamatergic synapse assembly and the temporal order in which specific molecules accumulate at new synaptic junctions. New presynaptic boutons capable of activity-evoked vesicle recycling were observed to form within 30 min of initial axodendritic contact. Clusters of the presynaptic active zone protein Bassoon were present in all new boutons. Conversely, clusters of the postsynaptic molecule SAP90/PSD-95 and glutamate receptors were found on average only approximately 45 min after such boutons were first detected. AMPA- and NMDA-type glutamate receptors displayed similar clustering kinetics. These findings suggest that glutamatergic synapse assembly can occur within 1-2 hr after initial contact and that presynaptic differentiation may precede postsynaptic differentiation.

Individuals with cervical spinal cord lesions (SCLs) typically depend on caregivers to manually assist in coughing by pressing against their abdominal wall. Coughing can also be assisted by functional electric stimulation (FES) applied to abdominal muscles via surface electrodes. Efficacy of FES, however, depends on precise temporal synchronization. The sniff controller is a trigger that enables paralyzed individuals to precisely control external devices through alterations in nasal airflow. We hypothesized that FES self-triggering by sniff controller may allow for effective cough timing. After optimizing parameters in 16 able-bodied subjects, we measured peak expiratory flow (PEF) in 14 subjects with SCL who coughed with or without assistance. Assistance was either manual assistance of a caregiver, caregiver activated FES, button self-activated FES (for SCL participants who could press a button), or sniff-controlled self-activated FES. We found that all assisted methods provided equally effective improvements, increasing PEF on average by 25 ± 27% (F[4,52] = 7.99, p = 0.00004 ). There was no difference in efficacy between methods of assistance ( F[3,39] = 0.41, p = 0.75 ). Notably, sniff-controlled FES was the only method of those tested that can be activated by all paralyzed patients alone. This provides for added independence that is a critical factor in quality of life following SCL.

Brain and nervous system development are experience dependent. Indeed, the sequence of development is laid out genetically, but early environmental events are major contributors to the system's development and optimal functioning. Various fetal injuries and birth trauma make babies vulnerable to developmental problems: cerebral palsy, seizures, abnormal muscle tone, delayed developmental milestones, sensory integration, and more. Our goal in the study presented here was to improve the neurodevelopmental track of babies at risk using Infant Neural Aquatic. Parent and baby dyads who met initial criteria were recruited for a 5-6 months intervention period through an open invitation, followed by a conversation and signing informed consent. In the beginning and end of intervention period, participants completed questionnaires, and developmental features of the babies were assessed using analysis of neuro-motor and vocal characteristics. Significant neurodevelopmental delta between values at the end and beginning of intervention period, comparing intervention and control, is described, and the strength of INA specific intervention tool is analyzed.

Autism spectrum disorder (ASD) is the joint name for neurodevelopmental impairments characterized by abnormal social interaction, communication difficulties, limited range of activities and areas of interest, and typical motor impairments. There is a remarkable increase in the prevalence of ASD over the past 30 years. Studies indicate that genetic, neurological, and environmental factors are involved in the emergence of ASD, and recent works describe the neuromolecular mechanism implicated in the basis of ASD. 3LT has now developed into a therapeutic procedure that is used for three main goals: to reduce inflammation, edema, and chronic orthopedic disorders; to promote healing of wounds, deeper tissues, and nerves; and to treat neurological injuries and pain. 3LT may treat neurological injuries by lowering levels of inflammation proteins and by stimulation of mitochondria to increase the production of adenosine triphosphate and neural growth factors. This review aims to discuss the current evidence for the effects and mechanisms of 3LT at the cellular level and the effects of 3LT-induced changes in brain development and function. Early and effective intervention, through the developmental time window of high ASD susceptibility, using tools that are directed to the mechanism of pathology, may minimize neurological and functional deficits.
