Brentford threw away the opportunity to claim only their second win of the year thanks to sloppy defending, and a failure to punish their opponents when in front.
Wally Downes made two changes from the 4-1 defeat at Luton Town, dropping Joel Kitamirike and Kevin O'Connor
for Andrew Frampton and Stephen Evans.
County opened the scoring in the twelfth minute, Darren Caskey the provider for Ian Richardson to head past Julian. Brentford's reply was only four minutes later, Ronnie Bull's cross from the left caught Tony Rougier by surprise, but his chest down landed straight into the path of the on-rushing Stephen Evans, who lashed the ball home from fifteen yards.
The visitor's went close eight minutes later, neat combination plat between Mickael Antoine-Curier and Paul Heffernan led to latter shooting just wide of Alan Julian's left-hand post.
With the clock on 40 minutes, Eddie Hutchinson gave the Bees a half-time lead. A Michael Dobson free-kick was briefly cleared by Frazer McHugh, but his header only reached Hutchinson, whose looping header beat the out-stretched hand of Stephen Garden for his fourth goal of the season.
After the break Brentford dominated the first fifteen minutes but could not force the crucial third goal that would have surely killed off County's challenge. They were made to pay for this in the 70th minute, County substitute Steve Scoffham flicked the ball over the challenge of Andrew Frampton to release Heffernan, who volleyed past Julian from five yards.
Worse was to follow with nine minutes left on the clock, Tony Scully cutting past Michael Dobson - rifling twenty yard shot home to give Notts their first back-to-back win in eleven months.
