In this case, they are x, which is one value in spike_train, and i, the enumeration variable that stores the current position in the list (iteration through the loop). The enumerate() function enumerates (counts) the items as it goes through a loop, so each time through the loop we have two variables being tracked. It’s a useful and compact way to iterate over some set of items to get them into a list. Take some time to break this down and understand it - there’s a lot going on! Recall that list comprehension is used to create a for loop in a single line, and return a list. This is a slightly more complicated list comprehension than we’ve seen in the past. Each value represents an evenly-spaced point in time (e.g., every 1 ms), where 0 encodes time points at which no action potential was detected, and 1 represents times when action potentials occurred: We can store the data from each trial in a list, spike_train. Data was sampled from the electrode every millisecond. On each trial, recording was started and then the 550 nm light was turned on 4 ms later, for a duration of 10 ms. When light of that wavelength is directed at the neuron, it tends to fire.įor this hypothetical experiment, we used an electrode to record action potentials from this optogenetically-engineered neuron to confirm that it tends to fire in response to 550 nm light. Imagine an experiment involving a neuron that was genetically engineered for optogenetics, meaning that it expresses genes sensitive to a specific wavelength of light (550 nm, which is green to learn more about optogenetics, check out this video by Prof. # Import libraries we'll need import matplotlib.pyplot as plt import numpy as np Our first spike train # Reading and Visualizing Structural MRI Data Working with Multielectrode Data in pandasĪveraging ERPs: Creating MNE Evoked objects Procedural versus Object-Oriented Plotting in MatplotlibĪccessibility and Human Factors in Plotting After that, he just has to be patient enough for his BSG to get onto the linebacker and make a cut off of their block.Introduction to Jupyter Notebooks in CoCalc He is reading the defender over the center, who takes an outside track. The quarterback takes a quick pass set and the running back shuffles to the A-gap. The tight end meanwhile is immediately climbing and getting square on the play-side linebacker. His job is to get square on that player and let the running back read the linebackers movement. When that doesn’t happen, he helps chip the nose defender onto the center on his way to the backside inside linebacker. The left guard takes a short pass set to prevent any blitz or spike by the backside defensive end. The center and guard that are to the side of the defender over the center are the ones critical to the play. Every lineman that has a player in their outside gap must move that player out of the inside vertical run lanes. The Colts are running a running back draw with a tight end insert to the play-side. ![]() ![]() Pass set with aiming point at inside number of edge rusherĪs a general rule, if there is a player in an offensive lineman’s outside gap, they must attach to that player and wash them out of the play.When the BSG is not to the side of the nose defender, they will be responsible for pass setting and washing any 3-tech or B gap defender.If the defender moves onto the guard, the center will climb to the second level.If they stay engaged, the center will carry them out of the play.Regardless of direction or spike, they must carry them out of the play.When the PSG is not to the side of the nose defender, they will be responsible for pass setting and washing any 3-tech or B gap defender.The center will then climb to the second level.If the player stays on the guard, they will wash them in the direction that the defender wants to go.If the player goes onto the center, they will climb to the second level.When on the side of the nose defender, they will pass set and combo with the center.Wash up and out to clear them from vertical seams inside.Pass set with aiming point at the inside number of edge rusher.
