Neonatal control of sucking pressures

Publication Date
  • Human Newborns Appear To Regulate Sucking Pressure When Bottle Feeding By Employing
  • With Similar Precision
  • The Same Principle Of Control Evidenced By Adults In Skilled Behavior
  • Such As Reaching (Lee Et Al
  • 1998A)
  • In Particular
  • The Present Study Of 12 Full-Term Newborn Infants Indicated That The Intraoral Sucking Pressures Fol
  • The Intrinsic Tau-Guide
  • A Recent Hypothesis Of General Tau Theory Is A Time-Varying Quantity
  • Tau(G)
  • Assumed To Be Generated Within The Nervous System
  • It Corresponds To Some Quantity (E
  • G
  • Electrical Charge)
  • Chang Ing With A Constant Second-Order Temporal Derivative From A Rest Level To A Goal Level
  • In The Sense That Tau(G) Equals Tau Of The Gap Between The Quantity And Its Goal Level At Each Time
  • (Tau Of A Gap Is The Rime-To-Closure Of The Gap At The Current Closure-Rate
  • ) According To The Hypoth Esis
  • The Infant Senses Tau(P)
  • The Tau Of The Gap Between The Current Intraoral Pressure And Its Goal Level
  • And Regulates Intraoral Pressure So That Tau(P) And Tau(G) Remain Coupled In A Constant Ratio
  • K
  • I
  • E
  • Tau(P) = K Tau(G)
  • With K In The Range 0-1
  • The Tau-Coupling Would Result In A Bell-Shaped Rate Of Change Pressure Profile
  • As Was
  • In Fact
  • Found
  • More Specifically
  • The High Mean R(2) Values Obtained When Regressing Tau(P) On Tau(G)
  • For Both The Increasing And Decreasing Suction Periods Of The Infants' Suck
  • Supported A Strong Tau-Coupling Between Tau(P) And Tau(G)
  • The Mean K Values Were Significantly Higher In The Increasing Suction Period
  • Indicating That The Ending Of The Movement Was More Forceful
  • A Finding Which Makes Sense Given The Different Functions Of The Two Periods Of The Suck
  • Ecology
  • Medicine
