刺激-反应

Because a stimulus does not suddenly become clearly detectable at all times at specific intensity, the operational definition of absolute threshold is the stimulus level at which a stimulus is detected half the time.

因为刺激并不是突然间在某种强度变得能轻易被觉察到，所以关于绝对阈限的定义是--能在一半的次数中被被试所觉察到的刺激水平。

VEP ; optimal stimulus ; threshold stimulus ; visual acuity

视觉诱发电位；最佳刺激；阈刺激；视力

He and the Pixar wizards send up superhero and James Bond movies while delivering a thrilling, supercool action movie that rivals Spider-Man 2 for 2004's best onscreen thrills.

This study was to examine at what level that the priming effects of task switching may occur.

目前有一种假说认为转换作业中的转换亏损成因是由於前项刺激对后项刺激产生正向及负向促发作用使然。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

It is a universal view that about electrical stimulation background and the current studying, and the principle of the tenderize meat and the electrical stimulation treatment improves meat tenderize.

Moreover, the protein level of pERK in the ACC was transiently increased after LTP induction, starting at 5 min and returning to basal at 1 h after tetanic stimulation.

取高频刺激后不同时间点的脑片进行免疫组化检测，结果显示，高频刺激后5 min时，pERK 表达显著升高，在10 min达到最高峰，1 h后回复到基础表达水平。

Electrical stimulation is well used in medical therapeutics,but the mechanism still needs to be studied further.

1引言电刺激在医学领域具有十分广泛的应用，人们对于电刺激的研究经历了十分漫长的过程。

"Once you decide to titillate instead of illuminate ... you create a climate of expectation that requires a higher and higher level of intensity" Bill Moyers

"一旦你决定用刺激而不是说明的方式…你就会创造出一种期望，希望这种刺激的强度越来越大"比尔·莫耶斯

After stimulating the peripheral endings of L2 DR with a train of square waves (0.8-1.2 mA, 100 Hz, 0.5 ms) for 2 s, the discharges at the distal end of transected L3 DR were recorded for 120 s.
