The first step comprises of sample preparation, imaging, and collection of histological slice data, while the second step consists of analyzing this histological data for measurement and quantification of labeled neurons, studying gene expression patterns, connectome exploration, etc. There are two steps in processing mouse brains. Over the past decade, neuroscience researchers have started studying the mouse brains due to their physiological and genetic similarity to humans, the ease with which their genomes can be manipulated, and the ability to train mice to perform behavioural tasks relevant to human cognitive processes. A salient example of this is the ongoing efforts in mapping the connections in Drosophila’s brain which has nearly 100,000 neurons. Only recently, with the advances in both computing power and optical imaging techniques, it has now become feasible to obtain the connectome of more complex brains. elegan, which consists of only 302 neurons took many years. Obtaining the connectome of even a simple roundworm such as C. However, obtaining the wiring diagram of the human brain is extremely difficult as it is large and contains billions of neurons forming complex interconnecting networks. If (Math.Abs(e.Location.X- _pressedPoint.X)= rectangle.X & point.X = rectangle.Y & point.Y <= rectangle.Y + rectangle.Understanding the brain connectome or the wiring diagram of the brain is essential to understand how the brain circuits work. Public override bool ProcessMouseUp(RenderControlMouseEventArgs e) If (e.Button = RenderControlMouseButtons.Left & IsPointInsideRectangle(_rectangle, e.Location)) Public override bool ProcessMouseDown(RenderControlMouseEventArgs e) Public override bool ProcessMouseClick(RenderControlMouseEventArgs e) Protected override void OnRender(RenderContext context, DrawingLayouts layout)Ĭontext.FillRectangle(, _rectangle) Ĭontext.DrawRectangle(new RenderPen(, 3), _rectangle) Ĭontext.DrawString(("T"),new RenderFont("Arial",20), _rectangle, new RenderStringFormat()) Protected override void OnCalculate(int bar, decimal value) SubscribeToDrawingEvents(DrawingLayouts.Final) Private Rectangle _rectangle=new Rectangle(30,30,150,50) Having redefined this method, the cursor could be returned depending on the mouse position.Įxample of working with these events: public class SampleKeyboardAndMouseProcessor : Indicator The GetCursor(RenderControlMouseEventArgs e) method is envisaged for this purpose. This logic is required for situations when there are a number of indicators in the chart and only one of them (the one that was the first to process the event) should process the event.Īlso, in some cases, depending on the mouse position, it is necessary to have a possibility to change the cursor. If the method returns ‘true’, it means that the indicator processed this event and there is no need to call this event in the following indicators. ProcessKeyUp(KeyEventArgs e) - processing the keyboard key releaseĮach of these methods should return ‘true’ or ‘false’.ProcessKeyDown(KeyEventArgs e) - processing the keyboard key pressing.ProcessMouseDoubleClick(RenderControlMouseEventArgs e) - processing the mouse double click.ProcessMouseMove(RenderControlMouseEventArgs e) - processing the mouse movement.ProcessMouseUp(RenderControlMouseEventArgs e) - processing the mouse button release.ProcessMouseDown(RenderControlMouseEventArgs e) - processing the mouse button pressing.ProcessMouseClick(RenderControlMouseEventArgs e) - processing mouse clicks.The following methods, which could be redefined in the indicator, are envisaged for these purposes: Indicators are able to react to the keyboard and mouse events.
