It all comes down to this. After traveling to the Pacific Northwest and beating two ranked conference foes, the USC women’s soccer team faces its biggest challenge of the year this Friday night: hosting the No. 1 UCLA Bruins.Striking distance · Senior midfielder Alex Quincey and the Women of Troy can stake their claim to an NCAA playoff berth with a win on Friday. – Striking distance · Senior midfielder Alex Quincey and the Women of Troy can stake their claim to an NCAA playoff berth with a win on Friday. The crosstown showdown will be played at the Los Angeles Memorial Coliseum this year, a fitting stage for what should be a huge matchup between two of the top three teams in the Pac-12 standings. On one side, UCLA (17-0-2, 9-0-1 Pac-12) is one win away from an undefeated season, while the Women of Troy (12-5-2, 6-4) are vying for an upset and an NCAA tournament berth.A win against the best team in the country would almost certainly clinch USC a spot in the national tournament, and though they have a solid chance to get in no matter what happens on Friday night, a victory would give the Women of Troy immense confidence heading into the postseason.USC’s confidence may already be surging, however. The squad showed its resilience when it responded to a three-game losing streak by traveling to Oregon and Washington the past two weekends and coming back home with wins in all four games. The two sweeps were crucial to the team’s postseason hopes, especially given the magnitude of this final home match.“Coming from the downward frame we were on, I thought finding results was absolutely imperative,“ head coach Keidane McAlpine said. “We needed to find victories and that was big for us.”Those victories not only gave the Women of Troy a confidence boost ahead of this match, but also a much-needed boost in the Pac-12 rankings, where they jumped from 10th place all the way up to third place in a matter of two weeks.“Any time you get wins in this league, you gotta think you’ve done something big,” McAlpine said. “It’s a huge step, and a huge positive toward the postseason.”In their most recent trip this past weekend, the Women of Troy triumphed over two top-25 teams in then-No. 17 Washington and then-No. 22 Washington State. Now, they’ll need to do the same against the top-ranked team in the nation if they want to defend their home pitch.The Bruins are one of the most dominant teams in NCAA soccer history. Not only have they progressed through their entire season undefeated, but they have also outscored their opponents 52-4 through 19 games. The team is riding a nine-game winning streak — taking place over the course of an entire calendar month — in which goalkeeper Katelyn Rowland has only allowed a single goal.On the other side of the ball, the Bruins are fueled by the remarkable play of midfielder Sam Mewis. Mewis is responsible for 25 of her team’s 52 goals, with 11 assists and 14 scores of her own. Also fueling UCLA’s attack are forward Taylor Smith and midfielder Sarah Killion, who have each slotted in seven goals.USC’s offense, on the other hand, has woken up since its three-game losing streak and has found the net six times in the last four matches. The Women of Troy are led by senior midfielder Alex Quincey, who has sparked the team off the bench with 10 goals. USC’s other scoring leaders include junior midfielder Jamie Fink and junior forward Katie Johnson.The Women of Troy undoubtedly know the stakes and what this rivalry entails, and even first-year coach McAlpine knows and understands the hype and excitement surrounding the Crosstown Cup.“Whenever you get a chance to play the No. 1 team in the country — UCLA aside — that’s an opportunity that you cherish,” McAlpine said. “It just happens to be UCLA and that just adds a little more to it.”Still, McAlpine says that both he and the team are still focused on their main goal from the beginning of their season. No matter who their final rival may be, they’re keeping their eyes on the real prize.“Our goal still stays the same — it was to get to the NCAA’s and to do well in the NCAA’s,” McAlpine said. “That’s our focus in this game, and it’s one more game to prepare us for that.”This rivalry match will kickoff under the Coliseum lights this Friday night at 7:30 p.m.

You have twin 125 megapixel video cameras in your eyeballs. Each pixel, a rod or cone connected to a neuron, sees only a small bit of the total image. How do these bits, like pieces of a jigsaw puzzle, fit together? Scientists at the Salk Institute have found that they are finely tuned to fit together for optimum clarity. Writing in PLoS Biology, they said,All visual information reaching the brain is transmitted by retinal ganglion cells, each of which is sensitive to a small region of space known as its receptive field. Each of the 20 or so distinct ganglion cell types is thought to transmit a complete visual image to the brain, because the receptive fields of each type form a regular lattice covering visual space. However, within each regular lattice, individual receptive fields have jagged, asymmetric shapes, which could produce “blind spots” and excessive overlap, degrading the visual image. To understand how the visual system overcomes this problem, we used a multielectrode array to record from hundreds of ganglion cells in isolated patches of peripheral primate retina. Surprisingly, we found that irregularly shaped receptive fields fit together like puzzle pieces, with high spatial precision, producing a more homogeneous coverage of visual space than would be possible otherwise. This finding reveals that the representation of visual space by neural ensembles in the retina is functionally coordinated and tuned, presumably by developmental interactions or ongoing visual activity, producing a more precise sensory signal.In the discussion, they added, “The present results demonstrate that the visual representation in the primate retina is finely coordinated to achieve a homogeneous sampling of visual space.” They pondered how this coordination is achieved. Is there a one-to-one correspondence between the dendritic field (DF) and the receptive field (RF)? Or are there overlapping layers of circuitry between that control the precision of the RF? Bipolar cells may do this, they said. Alternatively, inhibitory amacrine cells may tune the edges of RF shapes to prevent excessive overlap. They also wondered how this precision is achieved during development. Perhaps light produces cues that guide the RFs into position. Either way, the implications are surprising. It means that neurons don’t operate in isolation. They follow a precision code:The present results have surprising implications for how populations of neurons produce an efficient and complete representation. Recorded in isolation, single neurons frequently exhibit irregular response properties, suggesting that large populations must rely on averaging or interpolation to produce accurate sensory performance or behavior (e.g., see [37�39]). The present results, however, show that in a complete population, irregular features can be integral to a finely coordinated population code. This suggests that the nervous system operates with a higher degree of precision than previously thought, and that irregularities in individual cells may actually reflect an unappreciated aspect of neural population codes (e.g., ).This article was summarized on Science Daily, which stated, “scientists say their findings suggest that the nervous system operates with higher precision than previously appreciated and that apparent irregularities in individual cells may actually be coordinated and finely tuned to make the most of the world around us.”1.

It was all coordination, information, and encoding. As Theophilus Designsky said, Nothing in biology makes sense except in the light of design.
