Following spinal cord injury (SCI) for larval lampreys, descending axons of reticulospinal (RS) neurons regenerate, and locomotor function gradually recovers. In the present study, the electrophysiological properties of uninjured (left)-injured (right) pairs of large, identified RS neurons were compared following rostral, right spinal cord hemi-transections (HTs). First, changes in firing patterns of injured RS neurons began in as little as 2-3 days following injury, these changes were maximal at ~2-3 weeks (wks), and by 12-16 wks normal firing patterns were restored for the majority of neurons. Second, at ~2-3 wks following spinal cord HTs, injured RS neurons displayed several significant changes in properties compared to uninjured neurons: (a) more hyperpolarized V
; (b) longer membrane time constant and larger membrane capacitance; (c) increased voltage and current thresholds for action potentials (APs); (d) larger amplitudes and durations for APs; (e) higher slope for the repolarizing phase of APs; (f) virtual absence of some afterpotential components, including the slow afterhyperpolarization (sAHP); (g) altered, injury-type firing patterns; and (h) reduced average and peak firing (spiking) frequencies during applied depolarizing currents. These altered properties, referred to as the "injury phenotype", reduced excitability and spiking frequencies of injured RS neurons compared to uninjured neurons. Third, artificially injecting a current to add a sAHP waveform following APs for injured neurons or removing the sAHP following APs for uninjured neurons did not convert these neurons to normal firing patterns or injury-type firing patterns, respectively. Fourth, trigeminal sensory-evoked synaptic responses recorded from uninjured and injured pairs of RS neurons were not significantly different. Following SCI, injured lamprey RS neurons displayed several dramatic changes in their biophysical properties that are expected to reduce calcium influx and provide supportive intracellular conditions for axonal regeneration.

Spinal Cord Injury Significantly Alters the Properties of Reticulospinal Neurons: I. Biophysical Properties, Firing Patterns, Excitability, and Synaptic Inputs

Jun. 6--CHAPEL HILL, N.C. -- It could easily have been a transitional season for the University of Maine baseball team. Even coming off a 2005 season during which the Black Bears won the America East championship and won a game in the NCAA regional at Oxford, Miss., there were significant challenges. UMaine had to adapt to a new coaching staff headed by the energetic Steve Trimper, deal with the loss of its top two starting pitchers and utilize several freshmen in key roles. Yet the Bears were blessed with a talented group of veterans. Led by seniors Joe Hough, Ryan Quintal, Scott Robinson and Troy Martin, along with juniors Joel Barrett and Matt McGraw, the upperclassmen inspired the newcomers with their performance on the field and supported them with their leadership and guidance. UMaine had an outstanding season, finishing at 35- 22-1 while claiming its second straight conference title and earning another trip to the NCAA regionals. UMaine's season ended Saturday, when it suffered its second loss in the regional, 21-19 to North Carolina-Wilmington. "Coach Trimper and the whole coaching staff have done an amazing job this year really rebuilding the team and really making it his own and our own," Barrett said. "It's a testament to all of us and it's exciting for next year." Much of the Bears' success was derived from their potent offense. UMaine batted .325 as a team, averaging nearly eight runs per game. Seven regulars hit better than .300 led by sophomore shortstop Curt Smith, who ended the season at .390, the third best average by a UMaine hitter since 1990. He hit five home runs, knocked in 55 runs, led the club with six triples and stole 19 bases.
